dmesg would not be useful, it usually hits user programs. Like... mutt
suddenly displaying , instead of - in the header. Program failing to
start because function printg is not found (it was not exactly
printf->printg,  I don't remember exact symbol), ping complaining
about discarding corrupted packets, etc.

(Or of course, kernel oopsing or not going from suspend at all. But as
even user data are being corrupted, oops is not likely to be
interesting and system is typically not in state to capture it any more.)
