I can't seem to win.. with Xen... :-/
Ok, agp=no on the kernel command gets me past the agpgart crash listed
below. However... I am presented with another OOPS as soon as the kernel
in dom0 gets around to looking at my firewire-attached drives.
If I unplug my external firewire chassis, it actually completes booting
and everything seems ok.. However, the SECOND I plug my drives in, Xen
panics.. Here's the OOPS...
