[Xen-devel] qla2xxx driver failed in dom0 - invalid opcode: 0000 [1] SMP

["Brancato, Mike" <mike.brancato@xxxxxxxxxxx>]

I wanted to post this in case there is a real bug here.

The system this is on is running Debian Etch with the Xen packages from
Debian Unstable (currently 3.0.2+hg9697-1).  I am running all packaged
software so this is probably slightly out of date.

This is on an HP DL320 G4 with a Pentium D 930 processor.  I tried unloading
and reloading the qla2xxx module, but rmmod reported it in use, however it
did not seem to be used by any other module.

dmesg output below:

A soft reboot from the dom0 produced a successful load the second time:
