Dear Linux folks,
With an IBM S822LC with Ubuntu 20.04, after updating to Firefox 78.0,
using Firefox seems to hang the system. This happened with self-built
Linux 5.7-rc5+ and now with 5.8-rc3+.
(At least I believe the Firefox update is causing this.)
Log in is impossible, and using the Serial over LAN over IPMI shows the
messages below.

I have to warm reset the system to get it working again.
Kind regards,
