Dell D820 w Quadro NVS 110M Gentoo running kernel 4.19.x (see below) Mesa 18.2.8 and GIT (see below) Compiled with GCC 7.3.0 I've started trying to use nouveau since the Nvidia driver has finally been removed from Gentoo's repos. I had some bumps in the road attempting to use plasma, so I thought I'd give it a break and just use LXQT until I have to more time to diagnose those issues. It seems to work much more smoothly. However, I am seeing the odd lockup. It manifests itself in such a way that eventually I simply cannot open any new applications. Usually one is stuck in the background @ 100% cpu at this point. I cannot kill it even as root with signal 9. I have discovered that if I login to LXQT and just open a 15-20 konsoles, I can trigger the behaviour faster than under normal use. The only workaround at this point is a reboot. This kernel log was captured while running 4.19.14 kernel and mesa-18.2.8. I have since upgraded to 4.19.18 kernel and mesa-9999 (Gentoo language for GIT head). When I'm back in the office I'll attempt to break it on this configuration. I'm happy to recompile things, bisect, patch etc. since I already have all the source. Any help appreciated.

I made it lock-up using 4.19.18 with mesa-git. However, there may be two separate issues going on. This time, I did not get anything in dmesg after the event.
