2.6.10: dmraid gets mirror on HPT374 assembled wrongly

[Molle Bestefich]

Hi

HPT374 controller with four disks attached.
Two disks are in RAID0, two are in RAID1.

Works fine under Windows, but dmraid gets something
wrong, linux reports error and doesn't see partitions
on mirrored set.

Both disks have a standard DOS partition table, and
all partitions are FAT32 or ext2fs partitions.

An error is shown when running dmraid:

ERROR: dos: reading /dev/mapper/hpt45x_bbdfhdjicg[2]


Following is output from dmraid, I've tried to snip
out irrelevant parts.

# dmraid -a y -vvv -ddd
