Daily crashes with Nouveau

I used to have random crashes with a AMD FX8320, a few weeks ago I upgraded to a Ryzen as well as a new motherboard and I just keep getting crashes - multiple a day...

It's the type of crash that freeze all input, so I only am able to reset it with the power button.

I'd be grateful for any help or ideas

I see the following within journalctl at the time of crash:

Here is the dmseg output: https://gist.github.com/chrissound/0b33 … 5a59e47a94

These errors have been occurring on the Linux-lts kernel, I've just switched to the latest one and will report back if I get another crash...

Re: Daily crashes with Nouveau

If you launch a Webengine app or script, like chromium, with a
nouveau machine,

I get this message:

Nouveau openGL driver detected. Qt WebEngine will disable usage of the GPU.
Note: you can set the QT_WEBENGINE_DISABLE_NOUVEAU_WORKAROUND
environment variable before running this application, but this is 
not recommended since this usually causes applications to crash as
Nouveau openGL drivers don't support multithreaded rendering

But my browser or script still crash the machine sometimes even though it says that it will disable the gpu.
I still recommend running them with,

chromium --disable-gpu

That removes the problem for me, while using nouveau.

Problems not the kernel. Problem is nouveau.

Re: Daily crashes with Nouveau

Chromium is not a webengine app (it's engine Blink, is the backend for Qt Webengine, Chromium itself has no affiliation), so it will naturally not use that workaround by default.

Re: Daily crashes with Nouveau

Ok, I ran inox for a while and it would crash the machine without
the --disable-gpu flag. And inox is chromium. I was thinking that chromium was webengine. Anyway, inox would crash the machine without the flag.

Re: Daily crashes with Nouveau

Hmm

I see this message when starting up chromium: Created new window in existing browser session.
[9898:9926:0404/144101.694222:ERROR:browser_gpu_channel_host_factory.cc(120)] Failed to launch GPU process.

Re: Daily crashes with Nouveau

The non lts kernel does not seem to crash that often but every few days it does...
