           Summary: LTP fork05 test crashes dom0
           Product: Xen
           Version: unstable
          Platform: x86
        OS/Version: Linux-2.6
            Status: NEW
          Severity: major
          Priority: P2
         Component: Hypervisor
        AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
        ReportedBy: pl@xxxxxxxxxx


I noticed this in the xen-unstable build for today (May 4, 2005) but it may have
been in the preious day as well.  It rebooted after the crash, forgot to set
this machine up so that it wouldn't do that.  In any case, it just started
failing within the past few days at the most.

Here's the serial console dump:
