[Xen-users] Unable to locate IOAPIC for GSI 2

[C. Bröcker <c.brocker@xxxxxxxxxx>]

Hi,

I have two kernels

    vmlinuz-2.6.32-5-amd64
    vmlinuz-2.6.32-5-xen-amd64

As you can see, distributions are the same, the latter differs by loading
xen stuff.
When booting the xen kernel (vmlinuz-2.6.32-5-xen-amd64) I noticed a problem
which does not occur in the non xen kernel (vmlinuz-2.6.32-5-amd64).

[    0.000000] IOAPIC[0]: apic_id 0, version 0, address 0xfec00000, GSI 0-0
[    0.000000] ACPI: INT_SRC_OVR (bus 0 bus_irq 0 global_irq 2 dfl dfl)
[    0.000000] ERROR: Unable to locate IOAPIC for GSI 2
[    0.000000] ACPI: INT_SRC_OVR (bus 0 bus_irq 9 global_irq 9 low level)
[    0.000000] ERROR: Unable to locate IOAPIC for GSI 9

I think the problem is Xen related. I also noticed another problem while
booting the xen kernel.

(XEN) AMD-Vi: IOMMU 0 Enabled.
(XEN) I/O virtualisation enabled
(XEN)  - Dom0 mode: Relaxed
(XEN) Total of 12 processors activated.
(XEN) ENABLING IO-APIC IRQs
(XEN)  -> Using new ACK method
(XEN) TSC is reliable, synchronization unnecessary
(XEN) Platform timer appears to have unexpectedly wrapped 10 or more times.
(XEN) Platform timer is 14.318MHz HPET
(XEN) Allocated console ring of 32 KiB.
(XEN) do_IRQ: 1.231 No irq handler for vector (irq -1)
(XEN) Brought up 12 CPUs
(XEN) do_IRQ: 2.231 No irq handler for vector (irq -1)
(XEN) do_IRQ: 4.231 No irq handler for vector (irq -1)
(XEN) do_IRQ: 3.231 No irq handler for vector (irq -1)
(XEN) ...

I'm stuck here and need some help resolving this.

Best regards,
Hansa
