Comment 30 for bug 1872001

Hello all, i think i have the same issue. Encountered on Ubuntu 18.04 and kernels 5.3.0, 5.4.31, 5.5.16 and 5.5.6 (ppa mainline build). I'm in a virtualized VM with Proxmox
I can EASILY reproduce it within a minute (start Kodi for example).

Afterwards, i have such issues that will block the computer and need a reboot to solve:
