This patch started life as as479b, and has been rediffed. Please note the order of submission of this latest patch series -- even tho this has an older original number, it is the last patch I'll be sending today.
This patch changes the reported SCSI revision level to 2 for all disk-type
devices. This is needed in a few cases because the device reports a level
of 3 or higher but then crashes when given a REPORT LUNS command (for which
support is supposed to be mandatory at those levels). This shouldn't harm
us, since it only matters for sparse LUNs and we have separate ways of
coping with that.
Greg, please apply.

I think the problem is there's a nut loose on your keyboard.
