No, that's normal behavior. But you ought to be able to verify by
pinning Dom0's vCPU 0 to pCPU 0, and within Dom0 setting the
affinities of all interrupts to CPU 0 - that should make all of these
messages go away.

With two scheduler related changesets having got spotted as
problematic by now (23255:1f95b55ef427 and 23269:d67e4d12723f,
albeit the latter not really scheduler specific), I'm really very much
hoping for George to have an idea, the more that ...
