Hi
Following an update from 5.15.72 to 5.15.139 on one of my machines, the
console froze part way through the boot process. The machine still managed
to boot: it could be reached via the network and a keyboard-initiated
shutdown would do the right thing. The problem was that the screen remained
static the whole time: the X login did not appear. Only a reboot would
restore the display's functionality.
Comparing boot logs between these two kernels showed that 5.15.139 reported
the following messages not seen with 5.15.72:
thunderbolt 0000:04:00.0: interrupt for TX ring 0 is already enabled
WARNING: CPU: 0 PID: 713 at drivers/thunderbolt/nhi.c:139 ring_interrupt_active+0x218/0x270 [thunderbolt]
thunderbolt 0000:04:00.0: interrupt for RX ring 0 is already enabled
WARNING: CPU: 0 PID: 713 at drivers/thunderbolt/nhi.c:139 ring_interrupt_active+0x218/0x270 [thunderbolt]
radeon 0000:4b:00.0: Fatal error during GPU init
radeon: probe of 0000:4b:00.0 failed with error -12
The fatal error during GPU initialisation would be the reason behind the
frozen screen. I don't know if the thunderbolt warnings are significant.
A git bisect resulted in the following report:
d9ce077f8b1f731407e6b612b03bba464fd18d9b is the first bad commit
commit d9ce077f8b1f731407e6b612b03bba464fd18d9b

PCI: acpiphp: Reassign resources on bridge if necessary
[ Upstream commit 40613da52b13fb21c5566f10b287e0ca8c12c4e9 ]
It's taken me a while to work through the bisect process due to limited
access to the machine concerned. I see that in the last few days there have
been other reports associated with this commit. The symptoms on my machine
are different to the other reporters. In particular, I note that I'm
running the Linux kernel on bare metal.
For what it's worth, I also experienced the same problem when I tested 6.6.4
last week (the most recent kernel at the time of testing).
The output of lspci is given at the end of this post[1]. The CPU is an
"Intel(R) Core(TM) i7-5930K CPU @ 3.50GHz" which is not overclocked. Please
let me know if you'd like more information about the affected machine. I
can also perform additional tests if required, although for various reasons
these can only be done on Thursdays at present.
The kernel configuration file can easily be supplied if that would be
useful.
Regards
jonathan

looks like you are running downstream kernel, can you file bug report

For now offending patches are being reverted, so downstream bug will help
with tracking it and reverting it there.

full dmesg log and used config might help down the road (preferably with current
upstream kernel), as I will be looking into fixing related issues.
Perhaps a better way for taking this issue and collecting logs,
will be opening a separate bug at https://bugzilla.kernel.org (pls CC me as well)

I am running Slackware64 15.0. The kernels supplied by that distribution
are unmodified kernel.org kernels.

The patches will be reverted in Slackware as a matter of course when a
kernel.org "-stable" kernel with the fix is adopted. Slackware does not
apply any patches to kernel.org kernels. Nevertheless, I will raise a post
in the forum, hopefully later today.

Sure, will do. I'll be able to get the dmesg log from my earlier tests and
config easily enough. Testing with another kernel will have to wait until
next Thursday as that is when I'll next have physical access to the machine.
Which upstream kernel would you like me to test with: the latest "-stable",
or the most recent release?

current master branch that still has offending patches would do
(or any recent one with specifying commit id)
Also add:
dyndbg="file drivers/pci/access.c +p; file drivers/pci/hotplug/acpiphp_glue.c +p; file drivers/pci/bus.c +p; file drivers/pci/pci.c +p; file drivers/pci/setup-bus.c +p" ignore_loglevel

A bug has been opened at bugzilla.kernel.org as requested. The logs, kernel
configuration and the "lspci -tv" output (requested in a subsequent email)
have been added. The logs and kernel configuration are from the kernel.org
5.15.139 kernel. You have been added to the bug's CC. The bug number is
218268:
https://bugzilla.kernel.org/show_bug.cgi?id=218268
As mentioned, testing another kernel can only happen next Thursday. If
you would like other tests done let me know and I'll do them at the same
time. I have remote access to the machine, so it's possible to retrieve
information from it at any time.
Let me know if there's anything else I can do to assist.

lets wait till you can get logs with dyndbg='...' (I've asked for earlier)
and one more test with "pci=realloc" on kernel CLI to see if that helps.

It looks like pci_assign_unassigned_bridge_resources() messed up BIOS configured
resources. And then didn't manage to reconfigure bridges correctly, which led to
unassigned BARs => thunderbolt/VGA issues.
Something in ACPI tables must be triggering acpiphp hotplug path during boot.
Can you dump DSDT + SSDT tables and attach them to BZ.
PS:
to dump tables you can use command from acpica-tools (not sure how it's called in Slackware)
acpidump -b
which will dump all tables in binary format (so attach those or 'iasl -d' de-compiled ones)

Slackware doesn't provide acpidump AFAIK but it was easy enough to compile
from tools/power/acpi/tools/acpidump within the 5.15.72 tree I'd used
previously to build 5.15.72 (the kernel that's currently running). However,
running
acpidump -b
resulted in a segmentation fault. The root cause is line 339 in vsnprintf()
in utprint.c. With a workaround in place a functional acpidump was
obtained. I can provide further information from my analysis if it's
appropriate and you're interested.
For completeness I then tried the acpica source from Intel (version
20230628). The acpidump from this worked fine, and the files produced were
identical to those from my fixed kernel-tree acpidump. A tarball of these
is now attached to the Bugzilla report. Curiously enough, the corresponding
vsnprintf() line in the Intel acpica source distribution matches that in the
5.15.72 source. Perhaps the compiler flags in the Intel package happen to
prevent the segfault condition occurring at runtime for me.

I added the "dyndbg=" option to the 5.15.139 kernel command line and booted.
The resulting dmesg output has been attached to bugzilla 218268.
I also tested 5.15.139 with the "pci=realloc" kernel parameter. This was
sufficient to allow the system to boot without a GPU initialisation failure.
The dmesg output from this boot has also been attached to bugzilla 218268.
I used kernel.org's 5.15.139 for these tests because I already had it
compiled and was a little short of time. If you'd like me to repeat the
tests with a different kernel let me know which one and I'll see what I can
do. The Christmas break may delay this somewhat.

Thanks for collecting tables and debug logs,
I'll get back to you if more debug info or testing would be needed.
