Hi,
There's a new patch against 2.5.24 available at
http://www.gelato.unsw.edu.au/patches/2.5.24-lbd-patch

or can be pulled from bk://gelato.unsw.edu.au:2023/

With this patch large scsi discs are detected and sized correctly; and
it's possible create block devices using raid up to 16TB on 32-bit
platforms, and as large as you like on 64-bit platforms.

Tested at present on i386 and ia64.

The patch:
-- uses sector_t instead of int where blocks or sectors are
counted
(sector_t is either unsigned long or u64 depending on
CONFIG_LBD)
-- fixes bogus sign extensions when calculating scsi capacity
-- modifies the partitioning code so that EFI GPT at least can
specify partitions using 64-bit numbers.
-- Fixes the loop device to allow large backing files or devices,
and to fail gracefully if the backing file is too large.
