After upgrade to 5.11 get this multiple times per second on my C8000:

I know I have seen this at least once with a 32-bit kernel in qemu as well....
Not 5.11, but 5.10.11. 5.10.4 is fine. It could be a bad upgrade attempt,
I'll retry once I have built a proper 5.11 kernel.
Ok, it's there also in 5.11.2:
You don't see it in 5.11, but in 5.11.2.
Sadly none of the changes between those versions seem related
to this problem.
Do you still see this?
I'd like to get it anaylzed/fixed.
