Created attachment 125951 [details] dmesg output from startup with showed blocked processes I noticed that sometimes application like firefox, mvp and other qt5 apps stops launching. Already running applications are not affected. Steps to reproduce: Using Firefox is the fastest method to reproduce bug. 1. Launch Firefox instances until kernel oops. Last instance freezes.

I can rebuild kernel / libraries with debugging enabled if that would provide info that is actually useful.
This seems to be limited to NV50. I have the exact same setup on other systems with newer GPUs that do not exhibit this problem.
Give this[1] patch a try, it might be relevant. [1] https://github.com/skeggsb/nouveau/commit/8135089922f84c4ef7b47aeaa707490a2ee29a1d
I applied the patch from comment 7 to kernel 4.8.1 and the crashes are gone. There are new messages in dmesg: [ 230.257319] nouveau 0000:01:00.0: imem: PRAMIN exhausted [ 239.329904] nouveau 0000:01:00.0: imem: PRAMIN exhausted

It's a limited resource, and it's all been used. The driver will fall back to another (slower) method of accessing the data that it needs to map there.

Applied this patch to kernel 4.9.6 and since then haven't had any issues. Although I had no reliable way how reproduce the crash to 100% confirm patch's effectiveness, at least the patch seems to not cause any bad side effects. Tested on ~AMD64 Gentoo with G98M [Quadro NVS 160M]
