Oh... I see what happened.

That patch was fixing something which was accidentally 
left out of this patch:

http://marc.info/?l=linux-kernel&m=129840572232151&w=2

which I mistakenly thought was present in 2.6.38-rc7,
but it's not present (quite likely because without the
missing bit, it causes a panic), It's sitting in my stack of
patches still.

[scameron@...alhost linux-2.6.38-rc7]$ stg series | grep cciss
+ cciss-hoist-tag-masking-out-of-loop
+ cciss-inform-controller-we-are-using-32-bit-tags
+ cciss-mask-off-error-bits-before-calling-pci-free-consistent
+ cciss-remove-unnecessary-casts
+ cciss-fix-missed-command-status-value-CMD_UNABORTABLE
+ cciss-add-cciss_tape_cmds-module-parameter
+ cciss-fix-missing-initialization-in-scsi-cmd-stack-setup
+ cciss-export-resettable-host-attribute
+ cciss-fix-sense-data-copying-code

What needs to happen is I combine cciss-add-cciss_tape_cmds-module-parameter
and cciss-fix-missing-initialization-in-scsi-cmd-stack-setup into one 
working patch.

Sorry about that.  I need to slow down.  I'm making too many mistakes.
