Comment 5 for bug 1804505

I can add to this that I had lots of video lockups with 4.19.1, a day without was a wonder! Then I upgraded to 4.19.5 which did not help either. During one lockup I noticed that sound from a video was continuing to play for a while, so I tried to stick a flash drive into a USB port, and the drive was actually registered both being plugged in and removed again (syslog entries). Since the kernel seemed to continue to operate even when video was frozen, I thought this may be a MESA issue so I upgraded MESA using the Ubuntu-X Team PPA. That did not help either, so I upgraded to kernel 4.19.9 and this was a HUGE improvement in stability, no lockups for almost 2 weeks! But eventually it locked up, still with the same error being logged. Now I am on kernel 4.20, and there has been no problems for almost a week, but only time will tell... :)
