[Xen-bugs] [Bug 183] New: >1 virtual nics crashes domU

http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=183

           Summary: >1 virtual nics crashes domU
           Product: Xen
           Version: unstable
          Platform: x86
        OS/Version: Linux-2.6
            Status: NEW
          Severity: normal
          Priority: P3
         Component: Unspecified
        AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
        ReportedBy: dykman@xxxxxxxxxx


Running FC3 dom0 and domUs on x86, setting nics=2 causes a crash during domU
startup.
Setting nics=1, the domU starts fine and networking seems to be fine.
This config worked fine with an older build.
