Thanks for a clear report.  There have been some cciss fixes upstream
recently, though none of them seem particularly relevant.  Please test
v3.1-rc1 or later from experimental --- it should not require any
packages from outside squeeze except for linux-base and
initramfs-tools (which you can get from squeeze-backports).

If that fails, please send a summary of your findings to Stephen M.
Cameron <scameron@beardog.cce.hp.com>, Mike Miller
<mike.miller@hp.com>, and iss_storagedev@hp.com (addresses taken from
MAINTAINERS), and cc this bug log so we can track the resulting
discussion.

Hope that helps,
Jonathan
