Thank you. Unfortunately my question was rather pointless as the
Bugzilla instance at kernel.org still has not been set up again after
the security breach in August.

Therefore I reported this issue to FreeDesktop’s Bugzilla as #41503 [1].

I do not know. I though when the X server crashes or causes a Linux oops
then it is most likely a driver issue.

It would be great if someone with more insight can set the meta tags
appropriately and I am sorry for having to ignore your advise twice.


Thanks,

Paul
