Public bug reported:
Recently I put my Laptop into sleep mode like normal and later tried to wake it
up but the machine was unresponsive.
Interestingly opening the tty still worked (the second time it happened I
pressed ctrl+f1 immediately after I noticed the freeze) but as soon as I
interacted with the desktop environment (e.g. through a (normal) key press) the
system froze completely.
After a hard restart the same thing happened again after waking from sleep
mode. I couldn't reproduce it the following days.
>From the logs (see attachments), I would extract that the problem is already
>at the time of entering sleep mode. Anyway would be very happy if you could
>look into this BUG: kernel NULL pointer dereference.
