So I can see that I did screw up the debugging patch a tad, but the
information is still salvageable.
Adjusted from my "interesting" idea of printk formatting,
(XEN) **Pending EOI error
(XEN) irq 29, vector 0x2e
(XEN) s[0] irq 29, vec 0x2e, ready 0, ISR 1, TMR 0, IRR 0
(XEN) All LAPIC state:
(XEN) [vector] ISR TMR IRR
(XEN) [1f:01] 00000000 00000000 00000000
(XEN) [3f:20] 00016384 4095716568 00000000
(XEN) [5f:40] 00000000 4041382474 00000000
(XEN) [7f:60] 00000000 3967325758 00000000
(XEN) [9f:80] 00000000 2123395250 00000000
(XEN) [bf:a0] 00000000 1502837374 00000000
(XEN) [df:c0] 00000000 4270415335 00000000
(XEN) [ff:e0] 00000000 00000000 00000000
So Xen has been interrupted by an interrupt which it believes it has
already seen, and is outstanding on the PendingEOI stack, waiting for
Dom0 to actually deal with.
The In Service Register indicates (given the hex/dec snafu) that only
vector 0x2e is in service.
I will update my debugging patch with some extra information tomorrow.
