Thanks Lukas.
The patch has been tested with current kernel 6.3.0-rc5 on the same setup.
The deadlock between reset_lock and device_lock has been fixed.
See details in the dmesg log: dmesg_6.3.0-rc5_fix.txt in bugzilla:
https://bugzilla.kernel.org/show_bug.cgi?id=215590
Thanks,
Anatoli

I do not see a deadlock, when applying the following old patch:

Can we revisit the patches again to get a fix?
The issue still reproduce and visible in the kernel 6.2.0-rc8.
This old patch would need to be updated and reposted. There was a 0-day
bot issue and a question to be resolved. Maybe this is all already resolved,
but it needs to be posted and tested with a current kernel.
Lukas, can you resend that patch? We can test it.
I'm working on a patch which aims to solve these deadlocks differently,
by reducing the critical sections for which the reset_lock is held.
Please stand by.
Thanks,
Lukas
