[Xen-devel] Xen 3.3.0 - Assertion '!((irq_stat[(((get_cpu_info()->processor_id)))].__local_irq_count) != 0)' failed at xmalloc.c:180

["Christopher S. Aker" <caker@xxxxxxxxxxxx>]

This past weekend we rebooted two machines into 3.3.0. Just moments ago, 
within minutes of each other, they both crashed with the following:
(XEN) Assertion 
'!((irq_stat[(((get_cpu_info()->processor_id)))].__local_irq_count) !=

(XEN) Reboot in five seconds...

Both of the machines required a hard reboot, however the Xen console 
still responded.  Issuing an "R"eboot hung the box.
