Bug Description
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.
