[Xen-devel] #146571 - xen gets stuck at boot with "APIC error on CPU0"

[Rik van Riel <riel@xxxxxxxxxx>]

I'm writing this mail on behalf of Robin Green, who was friendly
enough to try the Fedora RPMs, and track down a Xen bug on his
system.

The bug report contains a workaround patch that shows a likely
place where the problem lives.  It looks like an APIC problem
on single CPU Athlon systems.

On boot, in the blink of an eye xen gets stuck in a loop, displaying

(XEN) APIC error on CPU0: 02(02)

over and over. Nothing else seems to happen.
