Public bug reported:
I have Ubuntu 14.04.4 with 'wily' HWE stack. File system i btrfs.
Whed I try to upgrade to wily, the systym crashes.
I get a black screen. I can't get to tty and Alt+SysRq+REISUB does not
reboot the system.
After a hard reboot the system does not boot either to 4.4 or 4.2 kernels.
Not with systemd or upstart.
Regarding btrfs, it does not have any errors and all snapshots can be
restored.
I saved a shapshot of the crashed system and I can provide any requested
logs. Now I reported from a restored system.
