There ya go. dmesg with drm.debug=0xff right to the point where I plugin to my dock and the driver dies: http://pastebin.com/0mWxZ1Nr > - Can you please decode a few symbols: > gdb drivers/gpu/drm/drm_atomic_helper.c > (gdb) break *drm_atomic_helper_check_modeset+0x2c5 I've never tried to debug a kernel module.

Two things: - Can you please boot with drm.debug=0xff and enable full debug output to the console with dmesg -n debug and try to recapture? I'd like to know what exactly happened right before. There should be lots of debug output right before the oops. - Can you please decode a few symbols: gdb drivers/gpu/drm/drm_atomic_helper.c (gdb) break *drm_atomic_helper_check_modeset+0x2c5 Please also paste around that line and indicate which one it is (since that always moves around).
