dmesg output

It happens after resume; sometimes it does not happen. It seems to be more
likely if RAM is full, although I have enough swap space.

The symptom is that X applications refuse to start, hanging in `drm_stub_op=
en`
(WCHAN column in `top`; status is `D` =E2=80=94 =E2=80=9Cuninterruptible sl=
eep=E2=80=9D). I can=E2=80=99t even
`kill -9` them: the command succeeds but nothing happens.

The first app to hang seems to be the screen locker; it locks the session b=
ut
fails to present anything on the screen, so I have to go to VT2 and use
`loginctl`. But VT switch becomes unreliable: switching from X to console
succeeds at second attempt (while switching back seems to succeed always).

Also I just found one app hanging in `nouveau_drm_preclose` (`D` too),
consuming zero RAM. (pid=3D6455, noticed in the log)

It=E2=80=99s strange but already running applications usually continue to w=
ork
properly.

I=E2=80=99ve noticed several Oopses in the dmesg output, hope that data wil=
l be
helpful.
