Hey @Michel, I'll chime in. I've had Radeon HD 7870 for se=
veral years now.
"ring 0/3 stalled for more than 10000+msecs" was my worst nightma=
re for quite
some time (see https://bugs.freedesktop.org/show_bug.c=
gi?id=3D65963).

Some Mesa versions were totally broken because of this happening way too of=
ten
(as in #65963). Most Mesa versions were good, as in: it doesn't happen *tha=
t*
often but still happens (e.g. every month or so). Such a low occurrence rat=
e of
the error makes debugging or bisecting not possible, thus it's not even wor=
th
reporting it here and taking Michel's or Alex's time. But yet - yes, it does
happen every once in a while.

Over the years, here's what I found to be a factor in ring 0/3 stalling, an=
d by
a "factor", I mean something that makes this problem happen a lit=
tle more often
than normally but still beyond reproducibility.

1. radeon.dpm=3D1
2. switching screens (CTRL+ALT+F1..F7)

Hope this helps, somehow.
