Heh, wrong sha.. $subject does however correctly identify in quotes the
origin of the threaded irq woes.

I already tested full revert.  I went looking for what busted kvm for
RT kernels, extracted the virtio series and quilt bisected that to use
shared interrupts.  I was going to just use my little turn off
multiport hacklet to put spinning kworker on the back burner until the
dust settled, but noticed that there was more going on, and none of it
is RT specific (thus freeing up a back burner).

From there, it's all test what you/Christoph post, as you post it, in
virgin source.
