I think I've been having the same issue as well, but I'm also not sure that this is 100% "new". The symptoms I'm having are consistent (mouse cursor continues to move, video freezes for ~2 seconds at a time leading me to think that the machine has crashed, GPU HANG and Resetting rcs0 log events, but machine is running underneath which is obvious because audio keeps working.) I can kill the offending video process (Zoom) and the issue subsides.
I can reliably reproduce the problem on 5.3.0-46-generic (Ubuntu 19.10 latest) and downgrading to 5.3.0-45-generic seemed at first to fix the problem. But I think that it's just less frequent on the previous kernels. I use my machine 5 days a week for 2-4 hours a day on Zoom. With the -46 kernel, simply launching a Zoom meeting kicks off the problem. However today after downgrading to the -45 kernel, while the problem doesn't immediately happen, it has "glitched" once where the machine had the same behavior for ~2 seconds and went back to working as expected.
Looking back over the last 3 months, these events - assuming that the "Resetting rcs0 for hang on rcs0" log event indicates the 2 second video glitch, it's been rather common. It's just *much* more common on the -46 kernel. Attached is a grep of journalctl since 2020-01-01 for the relevant log messages:
- kernel boot message to show the version
- i915 GPU HANG
- i915 Resetting rcs0 for hang on rcs0
Command: journalctl -o short-iso --since=2020-01-01 | egrep "Command line: |Resetting rcs0 for hang on rcs0|GPU HANG"
