           Summary: Hypervisor 3.0.4-1 crashes: Unhandled invalid opcode
                    fault/trap
           Product: Xen
           Version: 3.0.4
          Platform: x86
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Hypervisor
        AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
        ReportedBy: crubbert@xxxxxxxxx


I've got a problem with my Xen 3.0.4-1 Hypervisor crashing even before
loading the kernel, see the attached log. So far I couldn't find any
solution googling, in bugzilla, or on xen-users.

It's a Dual Athlon MP 2800+ System on a Gigabyte GA-7DPXDW-P with
4x512M ECC Infineon RAM. The dom0 is supposed to run Gentoo.
