[Nouveau] Linux 4.19 slowdown / crash - nouveau - Ubuntu 18.10 / Alienware 17 R5

[Christopher Patti]

Hi all. I've reported a bug over at the Ubuntu bug tracker: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1799180

Given the logs in kern.log it certainly looks like the nouveau driver is the culprit. The system becomes incredibly slow ultimately becoming unusable, and the fan screams.

Full details including driver / kernel version and full kernel log over at the bug, but I see a bunch of:

Oct 27 17:01:44 yamato kernel: [  402.710539] nouveau 0000:01:00.0: DRM: base-0: timeout

in the kernel log as the system slows down.

I'd love to assist in solving this problem. However I'm not a driver developer but I know C, can build kernels and follow directions really well :)

Also if there are any work arounds I'd love to hear them. I need to run the 4.19 kernel since my laptop crashes on sleep with prior versions.

Thanks in advance and apologies if this is an inappropriate venue for this question.

-Chris
