[XenPPC] Xen on JS21 - Dom0 rootfs on SAN

[David M Daly <dmdaly@xxxxxxxxxx>]

I consistently get an error booting
Dom0 from a SAN on JS21. I'm using xen_maple_defconfig + QLA2xxx device
driver. 

With an nfsroot boot argument passed
in, the system boots fine. 
With a root=/dev/nfs changed to root=/dev/sdc1
(a lun on the SAN), it mounts the root filesystem, and then fails with
the following message:

kjournald starting.  Commit interval
5 seconds
EXT3-fs: mounted filesystem with ordered
data mode.
VFS: Mounted root (ext3 filesystem)
readonly.

 <0>Rebooting in 180 seconds..Connection
closed by foreign host.

The two root filesystems are basically
identical, and I can boot and mount the SAN based filesystem as root for
a linux kernel (no Xen). 

This can be repeated on my test blade
cso86 (chassis 4 blade 6). I am using yaboot, and the failing configuration
is target cxeny2s.
