Hmm, okay that probably rules out those notifier changes then.

Hi Nick,
I tested these commits above today and all works with -smp 4. [1]
Smp 4 still doesn't work with the RC4 of kernel 5.13 on quad core
e5500 CPUs with KVM HV. I use -smp 3 currently.
What shall I test next?
Thanks,
Christian

Hi All,
I tested the RC5 of kernel 5.13 today. Unfortunately the KVM HV issue
still exists.
I also figured out, that '-smp 2' doesn't work either.
Summary:
-smp 1 -> works
-smp 2 -> doesn't work
-smp 3 -> works
-smp 4 -> doesn't work
Cheers,
Christian
