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? (In reply to comment #0) > Created an attachment (id=37466) [details] > dmesg > > Just updated kernel module to latest git and have a really bad screen > corruption on NV31 after kernel module is loaded. > > If you need a screen photo I provide it ... 58bbb63720c8997e0136fe1884101e7ca40d68fd is probably the culprit. 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/ Created attachment 37485 [details]
