Title:
Kernel Panic wrt btrfs while sbuild/schroot
Status in Linux:
Unknown
Status in linux package in Ubuntu:
In Progress
Bug description:
I'm running ubuntu Wily amd64 on a MSI Ghost Pro laptop.
I'm running btrfs on top of a bcached dmraid setup(intel software
raid0).
I can't use sbuild, cause it crashes.
I tried to use a schroot env, and when updating it I got it to crash
also.
All the keyboard/mouse/X11 are stalled, but I could ssh to it.
Trying to restart lightdm service didn't help.
I've got a kernel trace in the dmesg:
