Public bug reported:
I'm using 20.04 fully up to date on an Asrock N3700.
I'm getting random crashes every now and then. Total crash, no ssh or
anything (later I found out it's a kernel panic). Not tied to any app,
but it happened more often during gaming. Logs didn't show anything,
they just stop. I set up netconsole, with debug and ignore_loglevel in
the command line and I got this:

Title:
kernel panic on i915
Status in linux package in Ubuntu:

Bug description:
I'm using 20.04 fully up to date on an Asrock N3700.
I'm getting random crashes every now and then. Total crash, no ssh or
anything (later I found out it's a kernel panic). Not tied to any app,
but it happened more often during gaming. Logs didn't show anything,
they just stop. I set up netconsole, with debug and ignore_loglevel in
the command line and I got this:
