https://bugs.freedesktop.org/show_bug.cgi?id=105045 --- Comment #3 from Ilia Mirkin --- This happens because GPU fault recovery currently leaves the process in a totally broken state. (And all other processes that use the GPU, seemingly.) The general approach has been to try to avoid the GPU faults in the first place -- that will be printed before any of your other errors (i.e. before the nv50_cal stuff). Note that mesa 18.0 may have some relevant fixes, e.g. commit adcd241b563f44b2e3e92f5d840e2f617bc25836 Author: Ilia Mirkin Date: Mon Jan 1 14:54:17 2018 -0500 nvc0: ensure that pushbuf keeps ref to old text/tls bos Perhaps worth a shot. (This could hit if gnome-shell were generating tons and tons of silly shaders. Which it might be.) -- You are receiving this mail because: You are the QA Contact for the bug.
