            Bug ID: 105814
           Summary: Frequent Xorg lockups with GT710 after rad or write
                    faults
           Product: xorg
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
          Assignee: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
          Reporter: zarniwhoop-XZoyATsUNX5Wk0Htik3J/w@public.gmane.org

This is my second problem on my new machine (ryzen, GT710 (GK208B) - I needed a
vga connector), linux-4.15.12, gcc-7.3.0, glibc-2.27, mesa-17.3.7,
xorg-server-1.19.6, mouveau-1.0.15).

I am seeing frequent lockups in X (keyboard and mouse not working, but
MagicSysRQ works). Arguably this is similar to #104448, but I'm using "regular"
glibc.

There is no particular pattern to when this bug bites - the first time, I had
just built icewm, rerun startx, and was evaluating the various themes. Later, I
was installing firefox extension ublock-origin. As with the other bug I just
raised (105813) I tried using the modesetting Xorg driver instead of nouveau,
but the problem occurred again (left it compiling, came back to a frozen
xscreensaver). After that I turned off xscreensaver and it has now been up for
perhaps 2 hours, but will maybe go down again soon ;-(

From these failures I have extracted the following from my syslog, several (but
not all) show UNSUPPORTED_KIND. The 'scheduled for recovery' messages imply it
might self-correct, but it doesn't seem to.

(that last one was using modesetting, the others were using the Xorg nouveau
driver).
