If the boot drive is
a SATA then you must build it into the kernel, not as a
module
Such
as
CONFIG_SCSI_SATA=y
Make all the SATA related
as “y” in the .config and rebuild your xen kernel. If they are built as
modules they will not be loaded until the kernel is booted (and of course the
kernel cannot boot w/o SATA)

Subject: [Xen-users] Xen 3.1 kernel
panics on RHEL4u5
I am trying to install Xen
3.1 (with Linux kernel 2.6.18) from source on a machine running RHEL4u5
(2.6.9-55.ELsmp), but I am getting kernel panics. I've listed the KPs
below. The first listing is with an initrd image specified, and the
second one is without an initrd image. For the second listing, I am
only including the portion that differs from the
first.
With
initrd image:

Some of the threads I've
