Hi,
On Xen-unstable I encountered this non stopping logspam while trying to shutdown an HVM domain with
pci-passthrough:

etc. etc. etc.
The domain had shutdown perfectly well on earlier occasions, but this time it
kept running. It did drop from it's assigned 3 vpcu's to 1 vpcu, but it stalled
there.
The log spam only stopped by destroying the guest.
Since i haven't seen it before, it's probably hard to replicate.

And I saw as well with the latest unstable. Hadn't tried to narrow it down.
