            Bug ID: 464062
           Summary: Absolute freeze after hibernation and standby
    Classification: I don't know
           Product: kde
           Version: unspecified
          Platform: Other
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR

  Target Milestone: ---

SUMMARY
After waking up the system from hibernation the desktop freezes and becomes
completely unusable.
I have to force a restart.
Strangely sounds e.g. from a video playing, continue to play.

This happens every time after about 20 minutes of use.
This does not happen with a fresh reboot or boot, only after hibernation and
standby (tested "Standby" only once).

I tried to debug with GDB (both Kwin and plasmashell), but the logs show
nothing (empty).

"dmesg" shows:
1.  a recurring strange nvidia error, that also occurs when the freeze happens
(but it also happens randomly before that):
"[drm:nv_drm_fence_context_create_ioctl [nvidia_drm]] *ERROR* [nvidia-drm] [GPU
ID 0x00000100] Failed to allocate fence signaling event"

2. a segfault with firefox:
"firefox[3792]: segfault at d8 ip 00007f9aa2f40934 sp 00007ffd7de23248 error 4
in libX11.so.6.4.0[7f9aa2f31000+8b000]"

So it could be an Nvidia problem, nonetheless I wanted to report it here, maybe
you have some more ideas what and how I could debug or edit something.

STEPS TO REPRODUCE
Nothing specific seems to trigger it.

OBSERVED RESULT
Freeze.

EXPECTED RESULT
Work normal.
