--- Comment #16 from Petteri Aimonen (j...@kernelbug.mail.kapsi.fi) ---
I hit the same issue, using Ubuntu 20.04. It happened when switching window to
Firefox. For me it only crashed Xorg, ssh to the machine still worked ok.
Killing Xorg didn't work and `shutdown -r now` hung up somewhere.
Here is a bug report on the Ubuntu package:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1881134
Here is call trace decoded with the debug symbols:
