I think you need to use the "new ACK" method. When my x460 boots, the
above section looks like this:
(XEN) Total of 32 processors activated.
(XEN) ENABLING IO-APIC IRQs
(XEN) -> Using new ACK method
(XEN) ..TIMER: vector=0xF0 apic1=0 pin1=2 apic2=-1 pin2=-1
(XEN) ..MP-BIOS bug: 8254 timer not connected to IO-APIC
(XEN) ...trying to set up timer (IRQ0) through the 8259A ... failed.
(XEN) ...trying to set up timer as Virtual Wire IRQ... works.
I think if you add 'ioapic_ack=new' to your xen command line in grub.
I'm not sure if this is available in the testing tree or only in
unstable. The other thing to try is seeing if the machine boots on
xen-unstable.
