LinuxLists.cc - 2.6.13: Crash in Yenta initialization

Subject: 2.6.13: Crash in Yenta initialization

This does not happen in my current kernel (2.6.12-rc6 with Ivan's PCI bridge
patches applied). It is definitely localized in the Yenta code, since the
boot proceeds when I disable the Yenta config option. My hardware is an Acer
Travelmate 8104 with the external ezDock attached.

I can provide more info if you let me know what to look for.

I don't think any of the recent yenta changes would have caused this.

The .config might help.

Also, can you identify which line is going oops? Set CONFIG_DEBUG_INFO,
retest, do

gdb vmlinux
(gdb) l *0xc03af658 (the EIP value)

thanks.

Subject: Re: 2.6.13: Crash in Yenta initialization

As a follow-up to my previous mail, I collected a boot log of the working
kernel 2.6.12-rc6 with Ivan's bridge initialization patches below. The
crucial part seem to be the different bridge initialization sections:

2.6.12-rc6 + Ivan's patches:

Below the full boot log for the working 2.6.12-rc6+IvanPatches

I hope this additional info helps to bring this part of 2.6.13 up to the
earlier capability.

It's mysterious.
So 2.6.13 doesn't see cardbus bridge functions 06:09.1 and 06:09.3,
which means that these devices are not on the per-bus device list.
OTOH, they are still visible on the global device list, since yenta
driver found them. No surprise that it crashes with some uninitialized
pointer.

I'd suspect some change in PCI probing code between 2.6.12-rc6 and
2.6.13, but so far I'm unable to find what it was...

Maybe you could try 2.6.12 release and 2.6.13-rc kernels to see where
it breaks?
(Note that the PCI setup patches that you're using went into 2.6.13-rc2.)

Ivan.

Did you find the reason for this already?
We have a similar report:
https://bugzilla.novell.com/show_bug.cgi?id=113778
...
It dies in yenta_config_init because dev->subordinate is NULL.

Unfortunately, no.

Yes, this looks identical to Andreas' report.

Perhaps adding the line

#define DEBUG 1

at the very top of drivers/pci/probe.c could help to catch something
interesting in dmesg.

I had the same problem with an ACER 8101 WLMI. I reverted the initialization
partly and it works now, but I don't know if it really fixes the bug.
Something seems to wrong in the pci initcode.

But other hardware errors with the acer notebook still remain. The detection
of the ioapic results in a deadlock in the boot process (the
multiple-ioapic-fix or "noapic" solved this).

yenta related:
- pccard hardware is working now
- O2 Micro 4-1 cardreader is not working

Does someone have ideas, configs or patches for the cardreader? Do you need
more info? Let me know.

Thanks, that helped.

The reason was that Acer BIOS left only _two_ bus numbers available
for _three_ cardbus controllers, so pci_scan_bridge() assigns both
numbers to the first controller and leaves two other ones uninitialized.

Please try the patch here, but note that you'll apparently have only
one cardbus slot working. If you want more, use "pci=assign-busses"
boot option.

Igor,

I just had a chance to do some more testing, and the crash even occurs
in 2.6.13-rc2. I haven't had a chance to get serial console logs yet,
but I assume they will turn out similarly to the ones captured on
2.6.13 (glancing at the text as it scrolled by). So, something must
have changed between 2.6.12-rc6+patches and 2.6.13-rc2 (including the
patches).

Is there anything specific you want me to look for?

Yes, this patch fixes the oops. The pci= option doesnt help.

Subject: Continuing PCI and Yenta troubles in 2.6.13.1 and 2.6.14-rc1

Ivan,

I backported your Yenta fix into 2.6.13.1 (that's what I am currently using on
my production machine). However, the reliability of this setup is
significantly decreased over my previous 2.6.12-rc6+your PCI patches
configuration.

Specifically, the machine (Acer TM8104 notebook+ezDock docking station) now
often hangs (without an oops), sometimes during startup, sometimes a bit
later during use.

I have attached a console log of a successful start (ok26131.log), where the
machine lost access to the USB ports on the docking station (behind the PCI
Express/PCI bridge) later during normal use. I note that there are quite a
few more errors concerning the bridge initialization (compared to
2.6.12-rc6).

I attach a second log (stop26131.log) where the machine hangs during booting
in Yenta initialization.

I have also made an attempt to use 2.6.14-rc1 with your fix. However, two
things occur here: First, the machine is extremely unresponsive right after
booting (console input echoed with the speed of a 75 baud terminal [at
best ...]). Second, after some time, the USB ports in the docking station
disappear (with a message indicating PCI problems).

Thus, I believe there is still something rotten in the PCI code since the
2.6.12-rc6 days. Again, if you'd like me to run specific tests, please let me
know.

Andreas

Thanks a lot for the report.

You are right, and I believe the change that broke things is
introduction of pci_fixup_parent_subordinate_busnr()...

The patch here does two things:
- hunk #1 should fix the problems you've seen when you boot without
additional "pci" kernel options;
- hunk #2 supposedly fixes boot with "pci=assign-busses" option which
otherwise hangs Acer TM81xx machines as reported.

Please try this with and without "pci=assign-busses". If it boots,
I'd like to see 'lspci -vvx' for both cases.

Ivan.

Yenta patch is still needed (it will be included in 2.6.13.3).

These errors most likely mean that there are no interrupts form PCI
devices in the docking station. I'd suppose that massively changed bus
numbers make ACPI confused wrt interrupt routing, but all relevant IRQs
are exactly the same as without "assign-busses", so I'm puzzled...

At the moment I can only think of something like this: the PCIE-to-PCI bridge
(Intel 6702PXH) in your docking station also has IOxAPIC as PCI function #1,
but its config space is turned off by BIOS for some reason. However, its MMIO
registers are still present somewhere in PCI address space - we just don't
know where.
So there is a small possibility that we have accidentally stepped on them
and destroyed IRQ routing setup writing to MMIO registers of totally
unrelated device.

Please test this patch, though chances that it helps are quite small...
In either case lspci output will be useful.

Ivan.
