[Xen-users] [BUG] Assertion '(sp == 0) || (peoi[sp-1].vector < vector)' failed at irq.c:1173

[Håkon Alstadheim <hakon@xxxxxxxxxxxxxxxxxx>]

Getting crashes like the one below once in a while, shortly after boot,
on 4.10.0 rc*. What should I look for to debug? The box does have time
to create a VM or two before it happens. If all VMs are running
properly, it seems the assert will not be triggered at all.

It *may* be this only happens after warm restart, I tend to do a cold
boot when this is triggered, and I've never had them happen after that.

I'm reluctant to provoke this happening more than once in a while for
fear my raid will get out of sync (knock on wood), so I have not tested
my cold-boot theory extensively.

ALSO PASTED BELOW: xl info.

(side note: despite the last line there, the machine does not reboot
after 5 seconds ).
