** Description changed: I am able to reproduce a bug which causes a kernel panic when the following conditions are met: 1. Xubuntu 16.04 beta 1 is installed 2. btrfs is used as the filesystem 3. The intel-microcode package is installed after the initial system setup is complete I have got an actual photo of the screen when the crash happens as I was unable to locate the correct log file where this would have shown up.
