Title:
System fails to boot stuck on Scanning for btrfs
Status in linux package in Ubuntu:
Confirmed
Bug description:
Ubuntu 15.04 with 3.19.0-15-generic.
Current status:
System fails to finish booting with Scanning for btrfs. If you wait long
enough you see:
INFO: task exe:208 blocked for more than 120 seconds
....
INFO: task btrfs-transacti:230 blocked for more than 120 seconds
(message repeats every 2 minutes)
Ctrl-alt-delete does work to reboot system at this stage.
Booting with upstart still hangs.
Recovery mode fails to boot as well
Tried options system.debug-shell (from
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1444070) which got me a
few more details
Story of getting here: Was playing Team Fortress 2 and Internet went down.
Trying to get network-manager to reload caused some issues. Eventually decided
to reboot. Hung at reboot and ended up powering down by switch.
