RE: [Xen-users] Xen 3.1 kernel panics on RHEL4u5

I enabled all the SATA related options "y" in the .config and rebuilt the Xen kernel. I still got kernel panics. After examining the source of the ata_piix driver that comes with 2.6.18 (version 2.00), I noticed that my SATA controllers are not supported. What is the best way to include a more recent version (I need at least 2.00ac7) of that driver in my kernel? The documentation in the Xen manual for manually rebuilding the kernel is a bit sparse. Does anyone have a pointer to a more detailed description.

Thanks,

-Ryan

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

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:

Does anyone have any idea of what might be causing the kernel panics?
