[Xen-users] Kernel Panic in booting Xen 3.1 on Dell PowerEdge Server 1950

["Adit Ranadive" <adit.262@xxxxxxxxx>]

Hi,

Im having some issues with installing/running Xen 3.1 (source tree
from the 3.1 tree). The host OS is Red Hat 4 Update 5. Everything is
downloading and compiling fine.
The problem arises when I need to create an initrd.
The server comes with SCSI disks and Im not sure if this version of
Linux (2.6.18) supports them. I make the initrd with the follwoing
command:

mkinitrd -v -f initrd-xen.img 2.6.18-xen (i cannot use the
--omit-scsi-modules since i need them).

It loops on this "Looking for deps of ehci_hcd" . Ive tried changing
the config flags to build the required scsi modules into the kernel or
just as modules but it still gives the same error.
Also if I build it with the --omit-scsi-modules flag and boot into Xen
I get the Kernel panic error:

mount: error 6 mouting ext3
mount: error 2 mouting none
Switching to new root
switchroot:mount failed: 22
umount /initrd/dev failed:2
Kernel panic - not syncing : Attempted to kill init!

Any suggestions on how to fix the drivers to use the scsi hard disks?

Thanks,
Adit
