Occasionally I get the following Kernel panic on boot. This is running on the latest kernel but have seen it previously as well.
"Kernel panic - not syncing: IO-APIC + timer doesn't work! Boot with apic=debug and send a report."
I don't know who I am support to send a report to. But here is the log with apic=debug
Regards,
Scott

Nothing which rings a bell. Can you please provide a boot log from a
successful boot with apic=debug on the command line?
Also you might check whether there are BIOS updates for this board. The
early Ryzen BIOSes had some rough edges.

Will get someone to check for updates.
It's a remote system so don't have direct access to the EFI Shell right now.

Bios now updated to latest. Same kernel panic issue. Log below.
I think it is related to power cycling quickly.
Should APIC work if PC power cycled in a few seconds or is that the problem?

Yes, emphasis on should. Just to clarify, if you reboot it works and
cold start works as well if power was off long enough?

The working dmesg and the failing console log are hard to compare
because the latter does not contain debug level printks. Please add
'ignore_loglevel' to the command line parameters.

So far I have only been able to reproduce the issue by cold start with power off for only a few seconds
before re-powering the system. It has not failed via reboot yet that I remember.
Will have to keep my eye on whether using reboot is an issue or not.
And also keeping power off longer when doing a cold start.

Please find attached the failed console log with ignore_loglevel.

Weird.

Aside of the differences caused by the BIOS update there is nothing
related to the APIC/IO-APIC setup which is different between the working
and failing boot.
TBH, I have no idea what's going wrong there. Maybe Tom has one.
Thanks,

I asked around and was told this is most likely the motherboard has not
decayed its DC rails. So it's quite possible that keeping it powered off
for a longer period of time before powering back on may help.

It does appear that the APIC hardware or some other component does not reset
something and assumes the power up value is 0.
Too bad proper voltage monitoring/full reset is not in place.
I was just reporting the issue as instructed by the kernel panic.
I think the issue is avoided by leaving the system powered off longer.
