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 op 04-12-13 21:33, Shuah Khan schreef: > On Wed, Dec 4, 2013 at 1:02 PM, Michiel Janssens wrote: >> Thanks for your reply Shuah. >> Dmesg is beneath, I didn't find oops messages. >> Must say that I'm not familiar with kernel debugging. > Does /var/log/dmesg.0 have any suspend messages saves in it.
