Is this the same machine where the file /usr/bin/pulseaudio kept
disappearing from the filesystem, and you had to keep reinstalling
it (just pulseaudio, IIRC)?
That doesn't give much confidence in the hardware.
You wrote sometime ago, "on my laptop". Assuming that means you have
more than one machine, which is this? You could generate and copy a
file of diagnostic information to the other machine each minute
(incorporating a timestamp in the filename). It might not help if
everything falls over together.
My only other advice would be to check out the sleep states in the
CMOS, and errors in dmesg concerning the ACPI. There might be
something that bullseye is capable of using, that buster didn't,
and it just doesn't work correctly on this machine, and so it
falls into an unwakeable slumber.
Cheers,
David.
