Subject: Dom0 OOPS - causes restart
To: "xen-devel@xxxxxxxxxxxxxxxxxxxxx" <xen-devel@xxxxxxxxxxxxxxxxxxxxx>

Got an OOPS in dom0 (included below) that caused the machine to
reboot. Did a bk pull this morning (-r 1.1069). This is what I did to
get the oops.

a) loaded iSCSI drivers in dom0 (for the Intel 1000 Pro T iSCSI initiator)
b) Created a domain that used one of the partitions from the iSCSI
drive that was mounted (giving the 'phy:sda1,hda1,rw' option in the
domain config file). The domain uses the xen0 kernel image
c) Tried to run Postmark within the newly created domain (not dom0).

FWIW, I can run Postmark and IOzone just fine in dom0.

I also ran into another problem and I don't know if its related. When
trying to create a new domain (same config as specified above), I got
an OOPS in dom1 (not 0) just after the point when the kernel says its
trying to DHCP for addresses. However, I wasn't quick enough to
capture it. Could not reproduce the problem after a reboot.
