Public bug reported:
The system freezes at apparently random times with no warning and no
possibility to recover. The system becomes completely unresponsive and
has to be hard reset (which just corrupted my external storage). The
mouse cursor does not move and no keyboard input works. In particular,
Alt+SysRq+REISUB does not work (confirmed that it is activated and works
in normal conditions). Neither does Ctrl+Alt+F2. If a youtube music is
playing it gets stuck in a short repeat loop (stutter) then stops after
a while. The freezes have been happening for the past month or so at
intervals of about 1-3 days, not long after I installed Ubuntu 20.04 as
the first linux distro on this machine.
No program seems to be crashing before the freeze happens, and I have not found
any pattern of activity that can reliably trigger the freeze. It has happened
while surfing the internet or just viewing files. The kernel logs nothing
unusual before the freeze (please see the attached kern.log file; it contains
multiple instances of the freeze: look for where the system boots without
proper shut down beforehand).
I have tried switching between the open-source and the proprietary video
drivers. It didn't help. Also uninstalled xserver-xorg-video-intel with no
result, so installed it back.
Not sure what to try next. Very frustrating as the hard resets can damage
important work and data on disks.
