Can you reliably trigger that problem?

The issue happened to me 4 times out of 4 times I resumed 6.1.0-37 from hibernation.

Can you please test a 6.12 kernel (from testing or backports) and/or
6.15 (from experimental)?

6.12.32+bpo just resumed without a problem after echo reboot >

Bug#1107579 does indeed look similar. Since it seems to work for me, I
wouldn't mind running a kernel from backports as a workaround, but if
you need more information from me to help narrow it down, I can try to
gather it.
