kernel messages log
Sorry if this is drm error and not a nouveau error.
BUG: unable to handle kernel NULL pointer dereference at 0000000000000021
IP: dma_fence_wait_timeout+0x30/0x110
I had just started the computer, and started X with startx (because reasons).
I had opened the configure prefences when the mouse froze.
I'm including the kernel boot messages and traceback as an attachment.
