Message-ID: <529FA006.4030802@nexigon.net> (raw)

No suspend messages in dmesg.0
Tried earlyprintk=vga (incl keep) but nothing.
The screen does not go on, the system crashes before anything is
displayed, so it even does not get to the point of the password screen
for decrypting the drive.
Also followed the ubuntu debugging guide and tried sudo sh -c "sync &&
echo 1 > /sys/power/pm_trace && pm-suspend", but only lines found are:
[ 2.080414] Magic number: 9:73:293
[ 2.080445] tty tty26: hash matches
