Hi!

Thank you for all your efforts with this issue!

I am using the stock Fedora 34 kernel. The failures happen quite frequently. It varies from an hour to a couple of days before the hang, and it appens on all the IBM blades and less frequently on HP DL380 G7.

The servers run selenimm-controlled Google Chrome compiled by Google, and that produces some traps. They It's quite high load on them.

Here is a new trace looking a bit different. Maybe some clues in there?
