FWIW, there's a new driver for these devices now, called, hpsa, which is enabled on x86-64 for sure. See http://cciss.sourceforge.net/ for all the details. The main difference between the two is that hpsa is an scsi driver, while cciss is (was?) a block device. So _finally_ the mess with cciss devices is nearing its end. > Are you aware of specific examples of 64-bit capable servers that need > this driver? There are many examples of such configurations.

Yes that driver is somewhat large, but do we have size constraints? Thanks! /mjt
