6.12;bisected;regression - psi: inconsistent task state warning appeared in kernel log between 2e0199df252 and 54a58a787791 commits

[Mikhail Gavrilov]

Hi,
I spotted a new warning message when kernel
6.12.0-0.rc0.20240920gitbaeb9a7d8b60.7.fc42.x86_64+debug manded on my
machine.

Unfortunately, git bisect couldn't find the exact commit because the
follow commits 152e11f6df29, e1459a50ba31, a1c446611e31, 781773e3b680,
f12e148892ed, 2e0199df252a have FTBFS.

Anyway, I attached the full bisect log, kernel log with this warning,
and my kernel build config.
My hardware configuration is available by this link:

Peter, Valentin I see you as author and reviewer of these commits:
152e11f6df29, e1459a50ba31, a1c446611e31, 781773e3b680, f12e148892ed,
2e0199df252a.
Maybe you can dig into it?
