This does not occur with the prior kernel: 3.13.0-24-generic, nor does it occur with recent mainline: 3.15.0-031500rc8-generic_3.15.0-031500rc8.201406012235_amd64 Since this is a panic, I cannot run ubuntu-bug, uname, etc. However, the output of lspci is attached. The panic message (painstakingly hand-copied): Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block (0,0) CPU: 3 PID: 1 Comm: swapper/0 Not tainted 3.13.0-27-generic #50-Ubuntu Hardware name: ASUSTeK COMPUTER INC.
