Randy, 
Can you provide your configuration info? System type, controller type, etc. I am not able to reproduce this in my lab. -- mikem

System is an HP Blade, dual x86_64 (AMD) with hyperthreading, 8 GB RAM,
nVidia CK804 chipset.  The storage controller is this:

The problem just happened again on 2.6.27-git10.
The kernel boot log & config file for this are at:

along with lots of /proc files & lspci etc. from a good boot.

Yes, please continue to track. So far, I cannot recreate the failure so I may just have to take a stab in the dark and post possible fixes.

This currently only happens when loading a new kernel via kexec
and the first kernel is "old" (like 2.6.18; using 2.6.25 to load
the kernel-under-test works OK).
