Created attachment 130172 [details] 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_open` (WCHAN column in `top`; status is `D` — “uninterruptible sleep”). I can’t 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 but 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=6455, noticed in the log) It’s strange but already running applications usually continue to work properly. I’ve noticed several Oopses in the dmesg output, hope that data will be helpful.
