This is consistent with the symptoms I saw on my SuSE systems.  It
happened in both the 32 and 64 bit versions of SLES 8.

It is not a big problem for us to partition the big array into chunks
of 1 TB or less with the RAID controller, and present the partitions to
the host as different LUNs.  That's what we'll do for this project.
