Oh, actually, do you mean that this is still the same storm you could repro
before? And we do not have avoidance logic yet because you stopped being
able to repro the issue for a while?

Okay if so, but still I think there are some issues to deal with in the
patch. The avoidance logic for MSI delivery to a PV guest looks suspicious,
as I said in my previous email -- can the patch actually avoid storm
delivery to a PV guest?
