It looks like it doesn't happen with 5.7.0-050700rc7-generic. I cannot be 100% sure as it happened randomly. I have got, however, something suspiciously similar that has never happened before. It has happened several times already, as randomly as when I got a kernel panic before. Screen hangs for a while, but system stays alive. Logs show:

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: [77196.866485] BUG: unable to handle page fault for address: 0000000000a72860 [77196.866527] #PF: supervisor read access in kernel mode [77196.866535] #PF: error_code(0x0000) - not-present page [77196.866542] PGD 0 P4D 0 [77196.866552] Oops: 0000 [#1] SMP PTI [77196.866567] CPU: 2 PID: 1408 Comm: Xorg Tainted: P O 5.4.0-29-generic #33-Ubuntu [77196.866575] Hardware name: To Be Filled By O.E.M.
