Can't mount UFS2 partition, kernel has ufs2 support

[kimchi_sg]

I'm truly puzzled by this one.

Even though I have compiled in UFS / UFS2 support in the kernel, I still cannot mount my FreeBSD partition which is at /dev/hda1. Gentoo's / partition is at /dev/hda3. Every time I try to mount the FreeBSD slice, the "bad superblock, unknown filesystem or too many mounted filesystems" message appears. Before you ask, I have specified mount option "ufstype=ufs2" in both fstab and at the commandline, without success.

The strange thing is that I have successfully mounted FreeBSD slices on this system before. At that time, FreeBSD was on /dev/hda3 and Gentoo was on /dev/hda2. But I redid my Gentoo and FreeBSD installs with the same kernel options for UFS partition support, and now Gentoo can't mount the FreeBSD slice.

Anyone knows what might be the problem here? I can do without accessing my FreeBSD slice, but I really wonder why it has worked before and now it doesn't.

Here's my kernel .config with regards to UFS:

Has anybody resolved this cause I am having exactly the same problem.
