[Xen-users] Xen 3.1 kernel panics on RHEL4u5

["Ryan Persaud" <Ryan_Persaud@xxxxxxxxxxxx>]

Hello,

 

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 seen indicate that missing SATA support might be the culprit, but the SATA portions of my kernel configuration files seem to be identical in the relevant areas:

 

RHEL Kernel configuration:

# CONFIG_BLK_DEV_IDE_SATA is not set
