Subject: ahd problems in dom0 with Xen3 with dmesg
From: "John R. Shannon" <john%johnrshannon.com@localhost>

dom0 goes into a loop, on boot, where it dumps the SCSI controller
state. Computer has dual Xeon processors and dual SCSI drives.

dmesg output is attached.

The kernel is the same as XEN3_DOM0 except that ipsec and tmpfs are enable.
