Public bug reported: I just updated my ubuntu 11.10 with the latest kernel (3.0.0.19) and my xen hypervisor won't boot with this kernel.
... xen_register_pirq+0x82/0xe0 xen_register_gsi.part.4+0x4a/0xd0 acpi_register_gsi_xen+0x20/0x30 acpi_register_gsi+0xf/0x20 acpi_pci_irq_enable+0x12e/0x202 pcibios_enable_device+0x39/0x40 .... After some googling and digging around I found that a kernel patch is to blame "x86/ioapic: Add register level checks to detect bogus io-apic entries ". See https://lkml.org/lkml/2012/4/3/190 for more details. Apparently this patch has already been reverted in the default kernel for 12.04 (https://launchpad.net/ubuntu/precise/+source/linux/3.2.0-23.36), but not yet for the latest kernel for 11.10. Could you please also revert it in the 3.0.0.19 kernel.
