--- Comment #29 from zzyxpaw@gmail.com ---
Just hit this on Archlinux with linux-5.7.6 on a Vega 64. So far I've had three
crashes mostly occuring within the first few minutes of uptime. I'm not running
kwin or chrome, just a light window manager (bspwm) and compton.

During the first two, steam's fossilize was running which lead me to suspect it
was triggered by an interaction with that. However the third crashed before I
even managed to start steam, so either I'm just lucky or my system is good at
triggering this. @Duncan I'm not sure if you want to muddle your bisect results
with a different system configuration, but I'm happy to help test commits if
that would be helpful.

I've noticed the call traces reported in the kernel log are slightly different
for each crash; I'm not sure if they're likely to be useful or not. Here's at
least the one from my first crash:
