I noticed this in your kernel.log: [ 4.902810] [drm] nouveau 0000:01:00.0: GPU lockup - switching to software fbcon If you have an older kernel version that works, could you try bisecting this?

If reverting that commit solves the corruption, can you get me a BIOS dump [1] and a register dump? (after a fresh boot and before having loaded nouveau, you can use [2] to get one) [1] http://nouveau.freedesktop.org/wiki/DumpingVideoBios [2] http://cgit.freedesktop.org/~currojerez/tvdump/
