I have an IBM System x 3250 that successfully boots using the standard kernel (2.6.18-8.1.10.el5) but fails to boot with the xen kernel. The kernel appears to fail when it attempts to initialize the driver for the onboard SAS controller (LSI Logic / Symbios Logic SAS1064E PCI-Express Fusion-MPT SAS). Can anyone provide any advice? Here's the relevant info. Please let me know if any other information would be helpful.
