Thanks. Actually, the second case he sent has an interesting
difference:

(XEN)   s[0] irq 29, vec 0x26, ready 0, ISR 00000001, TMR 00000000, IRR 00000001

i.e. we in fact have _three_ instance of the interrupt (two in-service,
and one request). I don't see an explanation for this other than
buggy hardware. Sadly we still don't know what device it is that is
behaving that way (including the confirmation that it's a non-
maskable MSI one).
