[Xen-devel] Local apic support

[Patrick Scharrenberg <pittipatti@xxxxxx>]

Hey!

I still can't get apic support working on my nforce2-based board.
All my pci-cards and onboard-devices share only two irqs (irq 5 and 11).
Xen seems to find an apic but the wrong one since the system has an amd
duron and xen finds
> (XEN) Processor #0 Pentium(tm) Pro APIC version 16

Unfortunately I don't have a board with another chipset to look if it
works there.

What can I do?

Patrick
