Hi Peter,

For below patch, we couldn't find any connection between the code
change of kallsyms and xfstests testcase, but we got very stable test
results. We tested commit f1389181622a and its parent commit
7825451fa4dc for 12 runs each, parent was 100% good while this commit
was 100% bad, so we still send out this report FYI though we don't have
clear clue of the root cause. Please check the details below if
interested in further investigation. Thanks.

*groan* I'll go have a poke.

Also; I've had these patches in my queue.git for over a month now and
this is the first report, how comes?

Hi Peter,

Sorry about late report. We did catch this problem on
call-depth-tracking branch of queue.git in Semtember, but we used to
think it may be a false alarm since we cannot connect the code change
with xfstests, so didn't report at that time. After merged to x86 tip,
we did more tests and reviewed this problem with more developers, and
sent out the report finally.

dmesg starts at 42 seconds, you don't happen to have a complete one?

Sorry for the incomplete dmesg. Please check if attached kmsg.xz helps?
The time may vary a little since it is captured from another run.
Thanks.

Not sure if this has anything to do with xfs or testcases, so add
xfs folks to consult.

Hi xfs folks,

Could you please help check the original report at
https://lore.kernel.org/r/202210241508.2e203c3d-yujie.liu@xxxxxxxxx
to see if can find any clue for the problem? Thanks.

Sorry, wrong link. Should be:
