Someone submitted same bug on FDO bugzilla, but I think this is more kernel bug.. https://bugs.freedesktop.org/show_bug.cgi?id=102381 Did you try to bring this to the nouveau developer list? Not sure if the drivers developers look here. Did you consider to bisect this? (BTW: Thx for pointing me to this bug, I added it to this weeks regression report) Nouveau bugs, regardless of whether they lie in the kernel, Mesa or the Nouveau DDX, should be reported at bugs.freedesktop.org (see https://nouveau.freedesktop.org/wiki/Bugs/). You might want to add yourself to the freedesktop bug, as updates are more likely to happen in that bug report than this one. Updates to this bug report are sent to the dri-devel mailing list, but not every Nouveau developer follows it. I’ll give 4.14-rc3 a try on my laptop (Optimus + GK107 as well).

Not really, I am kinda busy with $dayjob so I just tried to report to upstream something useful. If I will get time, I will try to do this. Is this still happening? There was a patch recently to fix oops without fbdev emulation: https://git.kernel.org/torvalds/c/4813766325374af6ed0b66879ba6a0bbb05c83b6 (In reply to Thorsten Leemhuis from comment #5) > Is this still happening?
