i915 0000:00:02.0: Resetting rcs0 for hang on rcs0

Filing a new bug, as requested. Error file and contents of dmesg included.

Sometimes this happens with only IntelliJ open for 15 min, sometimes it happens when I've had 10 apps open for six or eight hours. Definitely happens less often under kernel 5.4.10-1-default than it did under 5.4.9-1-default.

I can usually drop to e.g., tty4 if I do it soon after the crash; never if I wait more than a few minutes. dmesg.txt dmesg_state.txt
