I've been getting an oops when shutting down my laptop (with /sbin/halt) or
rebooting it (/sbin/reboot or
/usr/sbin/kexec). Unfortunately, I can't provide the backtrace because it is on
the screen for only a moment before the
system shuts down/reboots.
I have however, bisected it and the outcome is:
cc27b735ad3a75574a6ab1a66ed6b09385e77e5e is the first bad commit
commit cc27b735ad3a75574a6ab1a66ed6b09385e77e5e

PCI/portdrv: Turn off PCIe services during shutdown
Some of the PCIe services such as AER are being left enabled during
shutdown. This might cause spurious AER errors while SOC is being powered
down.
Clean up the PCIe services gracefully during shutdown to clear these false
positives.

I'm confident that this is the correct outcome because a kernel built with the
preceding commit
(6018182d3158505f11103adaee8ffb53424df986) does not oops. Nor does -rc3 with
the patch reversed.
I'm more than happy to provide additional diagnostics and test proposed fixes.
As a starter for ten, I've attached the
output from 'lspci -v'. If, however, you need to see the backtrace, I'll need
some advice on how to capture that.
