With driver version
(II) intel(0): SNA compiled from 2.99.911-88-g58a757b
I experienced a *freeze* of keyboard (even numlock LED did not respond to
numlock key), mouse cursor and any screen change (old image is displayed) at
not good reproducible conditions. I did not recognize a pattern when exactly it
happens (it occured only three times, I think it was never in idle but when
starting a big program or doing some work inside a program).
Access to the machine via ssh and shutdown or kill of the X server is possible.
I had a look in the logs (Xorg.0.log and my system's journalctl) but did not
find any suspicious entry just before/at the freeze.
After this I had changed back again to the old version 2.99.910 for two days
and I did not experience a freeze anymore (as I never did up to last week).
Yes, the freezes may still have been caused by something else and randomness
may have caused no freezes since two days.
NEW:
Tested the version 58a757b again since one day and got a freeze today.
Attachments are from this one. Note that the freeze occured while I was running
a program under another user account (via `xhost +LOCAL:` and `su
username`). However, I remeber that one of the first freezes was while I was
working with a program under my user account.
Observation 1: X was still consuming a little bit of CPU (see htop attachment)
during the freeze.
Observation 2: Sound from a mp3 playing in vlc was continuing to play through
the speakers.
Observation 3: after a kill of X (along with all programs) and relogin
everything is fine again.
By chance I saw that during the freeze the mouse cursor was missing on my LVDS
although it should have been shown if I see correctly (see images
attached)(note that my external display is 1280x1024 and the LVDS is only
1024x768).
Attached also the requested stack and backtrace.</pre>
