Created attachment 132233 [details] Kernel dmesg without bug It happens every single boot. The system becomes unresponsive seconds after boot and the fan go to full speed until I force the system to shutdown. Sometimes the screen stays completely black, other times it shows the console login prompt (no X involved), but the system it's barely usable. Bisected the offending commit, and resulted this one: > commit 1e2115d8c0c0da62405400316f5499d909e479bc (refs/bisect/bad) > Author: Alexandre Courbot <acourbot@nvidia.com> > Date: Tue Dec 13 17:11:20 2016 +0900 > > drm/nouveau/pmu: instanciate the falcon in PMU device I attached the kernel logs with "nouveau.debug=debug" for both the previous and the failing commit.

I just find out what it seems to be a previous report of this bug (https://bugs.freedesktop.org/show_bug.cgi?id=101368). But because it doesn't have a clear fix, I'm not sure is the same.
Yeah, possibly the same bug. But now with a bisect, so much more likely to get fixed. The issue is [probably] that the newly called function makes calls to nvkm_falcon_rd32, which won't work at the ctor stage in optimus setups. So that logic needs to be reworked. I believe that Ben Skeggs is on it (at least we discussed it last night).
The bug has been fixed some time ago and no longer occurs. Thanks to all people involved.
