--- Comment #3 from Ilia Mirkin <imirkin at alum.mit.edu> ---
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.

    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.)
