So it looks like from your runs (before you had irqbalance):

(XEN)  MSI    31 vec=ad  fixed  edge   assert phys    cpu dest=00000023
mask=1/0/0
(XEN)  MSI    31 vec=ad  fixed  edge   assert phys    cpu dest=00000023
mask=1/0/0
(XEN)  MSI    31 vec=ad  fixed  edge   assert phys    cpu dest=00000023
mask=1/0/0
(XEN)  MSI    31 vec=ad  fixed  edge   assert phys    cpu dest=00000023
mask=1/0/0
(XEN)    IRQ:  31 affinity:00000000,00000000,00000000,00004000 vec:b5
type=PCI-MSI         status=00000010 in-flight=0 domain-list=0:273(----),
(XEN)  MSI    31 vec=39  fixed  edge   assert phys    cpu dest=00000020
mask=1/0/0
(XEN)    IRQ:  31 affinity:00000000,00000000,00000000,00000100 vec:39
type=PCI-MSI         status=00000050 in-flight=0 domain-list=0:273(----),

The affinity (and the corresponding vector) moves from one CPU to another
and then dom0 somehow does not get it. Do you have another of these
boxes available remotly to debug this further?
