Missing an OpenBSD partition when trying to mount in gentoo

[SiErRaZ]

Here is my situation:

Switched from OpenBSD to Gentoo yesterday on a system with 2 harddrives, hda with the OS and hdb with the data. I installed Gentoo on hda (so no more UFS partitions there) but now I want to access my data that is on hdb which is in 3 different partitions within the OpenBSD slice.

I can mount 2 of them with:
mount -t ufs -o ufstype=44bsd,ro /dev/hdb5 /mnt/bsdpartion

I can mount hdb4,5,6 (but 4 and 5 are the same partition) so I'm missing my 65GB data partition.

dmesg output show questionmarks where the last partition should be.

I'm having a similar problem. I just lost a machine (OpenBSD) and I wanted to recover data from the hard-drives, so I put them in my gentoo box and set up the kernel to support UFS and BSD disklabels. This is the gentoo 2.6.7-gentoo-r11 kernel btw. I have two hard-drives plugged in, one with 2 partitions in the slice and one with 3 partitions in the slice. On the drive with 2 partitions, I see 2 partitions, /dev/hde4 & /dev/hde5, which both show only the 1st partition's files when mounted. On the drive with 3 partitions, I see 4 partitions, /dev/hdf4, /dev/hdf5, /dev/hdf6, /dev/hdf7. 4 and 5 both show the 1st partition's files when mounted, 7 shows the 3rd partition's files when mounted. 6 gives 'mount: wrong fs type, bad option, bad superblock on /dev/hdf6 or too many mounted file systems' error when I try to mount it.

The appropriate dmesg output:
