           Summary: Hypervisor enters infinite loop at boot with "(XEN) APIC
                    error on CPU0: 02(02)"
           Product: Xen
           Version: unstable
          Platform: x86
        OS/Version: n/a
            Status: NEW
          Severity: major
          Priority: P2
         Component: Hypervisor
        AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
        ReportedBy: greenrd@xxxxxxxxxxx


(I reported this on the mailing list a few months ago, and on Red Hat bugzilla,
at https://bugzilla.redhat.com/beta/show_bug.cgi?id=146571 .)

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.

This is with the snapshot of xen-unstable of 20050522, as packaged by Fedora.
The following workaround patch has worked for me in the past with previous
releases, although I haven't tried it with this release yet:
https://bugzilla.redhat.com/beta/attachment.cgi?id=110399

This is the output of lspci -vvv from within Linux 2.6 running on a Xen patched
with the above workaround patch:
