Its probably significant that the problem appears at >137GB. I've got a
similar issue with a 320GB drive I've just tried to use. I've not pinned
down the limit but I partitioned the drive in two and the first half
works, the second half gives corrupt superblock errors when trying to
mount it (ext3).

I tried both the 2.6.19 version and one based on 2.6.20-rc4, same
problem. Is there anything specific the driver needs to do work with
disks > 137GB?

I've just tried to grab the datasheet but the Initio webserver has
chosen this moment to act up...
