Comment 16 for bug 1914573

It looks like the information we're missing is in /usr/lib/x86_64-linux-gnu/dri/iris_dri.so so please install:

  https://launchpad.net/ubuntu/+archive/primary/+files/libgl1-mesa-dri-dbgsym_20.2.6-0ubuntu0.20.04.1_amd64.ddeb

and then after the next crash and reboot, send us another:

  journalctl -b-1 > prevboot.txt

Or if you didn't need to reboot then please:

  journalctl -b0 > curboot.txt

Also, you don't need to rename .ddeb files. You can just install them with:

  sudo dpkg -i *.ddeb
