Take your time. I've a full plate of bugs to deal with :-(

So it thinks it is an edge, but if that IRQ is shared it has to be level. You
have
a really weird motherboard..
One more thing - can you boot the kernel as baremetal (so, no Xen) and "cat
/proc/interrupts"
and also attach the full serial bootup log? I am curious to see how the irq 5
is setup.
It should show up as level.
