I'm still leaving with this issue since my initial posting unfortunately :(

I'm wondering why PM support on this machine is so crapish (it initialy
oopsed when resuming due to a bug in rtsx driver).

Thanks

Is this a new problem in 3.12?

I also have an affected laptop where the network and MMC controller
vanishes on resume. The laptop is also from Clevo, but a different
model: Clevo B7130. I had no issues with my custom kernel
configuration (latest version that I tested was 3.13.1), but at least
the stock Arch kernels from 3.12.2 up to 3.12.6 and 3.13.1 are
affected by this issue.

Reproduce with:

1. Boot system.
2. lspci -nnvt > lspci-nnvt.txt
3. Suspend system (lid close)
4. lspci -nnvt > lspci-nnvt2.txt
5. Observe missing network controller (see diff below).

The only difference now is the kernel config. I guess that it comes
from CONFIG_HOTPLUG_PCI. In my non-broken config, it's unset. The
Arch kernel sets CONFIG_HOTPLUG_PCI=y (and also
CONFIG_HOTPLUG_PCI_ACPI=y).

That guess is based on the additional messages I see with the broken config:

[ 1.033628] pci_hotplug: PCI Hot Plug PCI Core version: 0.5
[ 1.033642] pciehp: PCI Express Hot Plug Controller Driver version: 0.4

Before I start bisecting, do you have any ideas to debug this?

The stock config of Arch Linux kernel 3.13.1-2-ARCH can be found on:

Well, I suspected that it would result from hotplug changes.

Please send me a dmesg log including the suspend-resume cycle after which the
device is missing.

Thanks!

Damn, I was hoping you'd have found a workaround for this by now. It is
quite severe though!

> I'm wondering why PM support on this machine is so crapish

My quick research turned up a few results ([1],[2],[3]) for similar bug
with other setups, however there are rather old and not met with a fix.
But yeah, this machine has some undeniable defects, a faulty BIOS made
me RMA it just after its purchase.

I was also hit by the rtsx driver bug
(https://bugs.archlinux.org/task/37720) and was delighted with its fast
resolution. I was hoping that its fix would also address the
disappearing Ethernet bug.

Le 06/02/2014 13:40, Rafael J. Wysocki a ?crit :
> Is this a new problem in 3.12?

There is a ticket in kernel bugzilla [4] that involves r8169 and
suspend/resume or rather hibernate/resume. This bug involves kernels
prior to 3.12, but I can't tell if it is really related.

3.12.x is the first and only kernel I tried on this machine (well I do
have Debian 7 in dual boot but I haven't used it since I installed it).

Would it help if I'd try another distribution with older kernel? If so,
would doing it from LiveUSB be a valid way?

Please find it below. The only details I have stripped are UUID and
MAC addresses. Let me know if you need more information.

Please send the output of lspci -vv right before suspend and right after
the subsequent resume as attachments.

yeah, but calling this "fast resolution" is quite incorrect.

I don't blame anyone for this and I'm quite happy that a workaround has
been found at last but calling this "fast resolution" is a bit funny
compare to the PITA it was to debug this.

That's probably why I haven't tried to do a similar work for this bug.

Thanks.

See below. The MAbort+ looks suspicious. 00:1c.1 is the parent of the
devices on bus 4.

I forgot to mention a workaround, by triggering a rescan, the
devices become alive again. Here is a log from 3.12.7 (different

Not sure what the integrated graphics device at 00:02.0 shows up here,
but ok. This trace is shown every time the rescan is triggered (manually)
after resume.

Some times, the "enabling device" lines are not shown, and the messages
start with the following instead:

OK

It looks like we fail to resume the device, then, for some reason.

That may be a PCIe link issue or something similar.

Is this a regression for you? If so, what's the last kernel that didn't
have this problem? Does 3.13.y (as released by Greg, without and distro

It was a regression from 3.11.x to 3.12 (and it is still broken with 3.13).
Due to some mistakes from my side, I have tested more configs:

(based on Arch Linux 3.13.1 x86_64 config)
(a) 3.13.2 with CONFIG_HOTPLUG_PCI=y, but CONFIG_HOTPLUG_PCI_ACPI=n works.
(b) 3.13.2 with CONFIG_HOTPLUG_PCI=y and CONFIG_HOTPLUG_PCI_ACPI=y is broken.
(c) 3.13.2 with CONFIG_HOTPLUG_PCI=n still works.
(my stripped config)
(d) 3.13.2 with CONFIG_HOTPLUG_PCI=y, but CONFIG_HOTPLUG_PCI_ACPI=n works.

With CONFIG_HOTPLUG_PCI_ACPI=y, the only difference in dmesg is:

(during boot)
acpiphp: ACPI Hot Plug PCI Controller Driver version: 0.5
(after resume)
iwlwifi 0000:05:00.0: no hotplug settings from platform
xhci_hcd 0000:02:00.0: no hotplug settings from platform
(here, NetworkManager complains that a device has gone)
iwlwifi 0000:05:00.0: no hotplug settings from platform

Of course, with config (b), the ethernet adapter vanishes while it is still
present with configs (a), (c) and (d).

Time to do a bisect?

You'll find them attached, but I got a strange error when I wanted to
run it as root:
$ sudo lspci -vv > lspci_vv_before
pcilib: sysfs_read_vpd: read failed: Connection timed out
$ sudo -i
# lspci -vv
pcilib: sysfs_read_vpd: read failed: Connection timed out

So I only got the unpriviledge output.

Some complementary lines from my journal:

And one I thought of interest:

kernel: rtsx_pci 0000:03:00.0: vpd r/w failed. This is likely a
firmware bug on this device. Contact the card vendor for a firmware update.

That came three times before suspend.

Only two lines about hotplug, none special.

Stripped journal attached for the suspend cycle.

Sorry, I didn't mean to underestimate the amount of work you put in that
bug resolution (actually it was the first time I heard of kernel
bisection and was pretty impressed by how you led it).
What made me say it had been a fast resolution is that its fix was
included right in the next kernel revision, which I found to be quite
diligent. But the actual work to find it, the kernel bisection, that
must have been a real sweat.

That most likely would single out one of the ACPIPHP commits without giving us
much clue about what's going on.

I fail to see what the connection between those changes and system resume is,
however.

Please replace all pr_debug() calls in hotplug_notify() with pr_info() and
see if you get any events from there.

Thanks!

I think I have seen such an error before, but I cannot find it in the logs
that were obtained a while ago. Failure to read VPD should not cause issues.

I think this is relevant. See also my test with 3.13.2 and different
kernel configs[1]. A workaround that triggers a scan was also posted[2].

I could not find a hotplug_notify function in the kernel tree, but I
have dyndbg enabled. Booting with `pci_hotplug.debug=Y
pci_hotplug.debug_acpi=Y pci_hotplug.dyndbg acpiphp.dyndbg` gives me
only a few acpiphp_glue messages. After resume:

Could the following commit have something to do with it?

commit 4ebe34503baa0644c9352bcd76d4cf573bffe206
Author: Rafael J. Wysocki <[email protected]>
Date: Tue Jul 16 22:10:35 2013 +0200

ACPI / hotplug / PCI: Check for new devices on enabled slots

The current implementation of acpiphp_check_bridge() is pretty dumb:
- It enables a slot if it's not enabled and the slot status is
ACPI_STA_ALL.
- It disables a slot if it's enabled and the slot status is not
ACPI_STA_ALL.

This behavior is not sufficient to handle the Thunderbolt daisy
chaining case properly, however, because in that case the bus
behind the already enabled slot needs to be rescanned for new
devices.

For this reason, modify acpiphp_check_bridge() so that slots are
disabled and stopped if they are not in the ACPI_STA_ALL state.

For slots in the ACPI_STA_ALL state, devices behind them that don't
respond are trimmed using a new function, trim_stale_devices(),
introduced specifically for this purpose. That function walks
the given bus and checks each device on it. If the device doesn't
respond, it is assumed to be gone and is removed.

Once all of the stale devices directy behind the slot have been
removed, acpiphp_check_bridge() will start looking for new devices
that might have appeared on the given bus. It will do that even if
the slot is already enabled (SLOT_ENABLED is set for it).

In addition to that, make the bus check notification ignore
SLOT_ENABLED and go for enable_device() directly if bridge is NULL,
so that devices behind the slot are re-enumerated in that case too.

This change is based on earlier patches from Kirill A Shutemov
and Mika Westerberg.

This one, or another one in that series. I rather suspect

ab1225901da2 Revert "ACPI / hotplug / PCI: Avoid doing too much for spurious notifies"

from Mika, but it really doesn't matter.

Can you please check the patch below (it is on top of 3.14-rc1, but I think it'll
still apply to 3.13) and report back?

Unfortunately, the adapter still vanishes. dmesg is below this message.

After the last message, NetworkManager loses the interface within a second.
The next following messages follow two seconds later and are unrelated
(those are about wireless connectivity).

No problem Bastien and don't be impressed by this :). Bisection thing is
a mechanical work but can be useful sometimes when we, users, are lost
and have no clue on what's going on.

The real PITA in that case was to reboot more than 10 times the system
in order to test each suspicious commits on a live system.

Anyways, good luck, all my hopes are on you now :)

Anyway, the message you've added to the patch is not printed for this bridge,
so the condition is not satified for its bus. We need to find out why it isn't
satisfied and what exactly happens to the devices that appear to go away.

Please apply the appended patch instead of the previous one and check the output.

Thanks,
Rafael

One thing, I noticed when checking the DSDT:

Device (J380)
{
Method (_STA, 0, NotSerialized) // _STA: Status
{
If (LNotEqual (DVID, 0xFFFFFFFF))
{
Return (0x0A)
}
Else
{
Return (Zero)
}
}

_STA() returns 0x0A instead of 0x0F. Could there be something missing in
the ACPI hotplug code that overlooks this and removes the device on resume?

That is possible. Actually even quite likely, but let's wait for the response
from Peter.

Here's a hack that should take the 0xa return value into consideration. It
turned out that this case is even mentioned in the ACPI spec.

Looks reasonable.

Peter, please check if this one makes a difference for you.

Thanks, I can confirm that triggering a rescan by issuing

sudo tee /sys/devices/pci0000:00/0000:00:1c.1/rescan <<<1

made the device reappear on my system (of course I had to adapt the
command to match PCI Bridge number). That's a handy workaround, it
avoids restarting each time.

As I've never compiled a kernel so far I think I'll leave the
configuration tweaks for another time :)

Cheers

This works, the devices are not lost anymore after resume. dmesg
mentions the 04:00.* devices at resume compared to the unpatched kernel:
