There is no guarantee that a more recent, unsupported kernel like 2.6.32 will work on an userspace built around 2.6.18, especially if you are making use of the Xen Hypervisor and other components. There can be some "breakable" modules when you're running 2.6.32, 3.0, etc... on the EL5/2.6.18 kABI ;) > The kernel boots fine and initrd kicks in.

Does anyone know > any issue with mptsas or a way to debug the problem? How did you verify the mpt* stack actually loads if it kernel panics? Did you see it scroll past? Did you try booting the old kernel, and breaking out the initrd (e.g., "gzip -cd initrd.img | cpio -imdv") ? It probably wouldn't hurt to do some comparison of the init and modules between your working 2.6.18 and the "problematic" 2.6.32. -- Bryan J Smith - Professional, Technical Annoyance _______________________________________________ rhelv5-list mailing list rhelv5-list@redhat.com https://www.redhat.com/mailman/listinfo/rhelv5-list
