<pre>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.
