Question

linux

Linux Mint 4.4.0-177-generic x86_64 (64 bit) 18 Sarah Hangs
from time to time when starting some application. The mouse cursor is and moves, the hard drive shows some kind of weak activity, everything else hangs. In the logs this is:

Nov  5 12:09:05 team kernel: [55821.272512] nouveau 0000:01:00.0: fifo: DMA_PUSHER - ch 8 [advanced-rest-c[16601]] get 0000000000 put 0000000000 ib_get 00000000 ib_put 00000002 state c0000000 (err: MEM_FAULT) push 00400040

What would that mean?

Answer 1

A poor free driver for the video card hangs.
Put the normal proprietary one.
Instructions are googled for any video card and distribution.
