Hi Christian,
Thank you for your reply!

Yes, I will try to check that next week.

Thanks!

Sorry, I forgot to mention that. Yes, it is the guest kernel.

I have one kernel selftest that causes the crash. But I need to run it ~200 times to have a high chance of saying I don't have the crash with this environment. But that's quite reliable.
From what I understood, we have this issue because some instructions are not serialised, so we don't have an issue all the time, it depends on the sequence.

I already built the 8.2 version. I can look at building more versions (but not the full releases with .deb packages)
