Yeah. I came to that conclusion as well.

And in fact when booting with init=/bin/bash, it isn't even loaded at
all, but that doesn't help unfortunately.

OK. Rebuilding now. I configured a kernel log buffer size of 524288
(shift 19) so that should be good and big.
When done, I will boot into single user mode again and do a suspend/
resume and save the dmesg output and attach it here (or post it somewhere
and point to it here). Of course, I can't send the dmesg from the second
cycle as it's dead after the second cycle resume.
If only this (what's turning out to be a POS) laptop (that's going back
to the store if this does not resolve fairly soon) had a serial port I
could get a serial console and capture that.
