mount ext2fs

[Johnny]

i'm trying to mount ext2 partitions from an install of rh8 on my freebsd box. simple process i'd think, but apparently not with the current setup. the bsd box is 4.8-stable with a custom kernel including the ext2fs module, so i'd like to think that isn't the source of the problem. here is some output on the issue:

euphoria# fdisk ad2
...
The data for partition 2 is:
sysid 131,(Linux filesystem)
start 211680, size 88814880 (43366 Meg), flag 0
beg: cyl 14/ head 0/ sector 1;
end: cyl 1023/ head 239/ sector 63

euphoria# mount -t ext2fs /dev/ad2s2 /data2
ext2fs: /dev/ad2s2: Invalid argument

all of the directories are in place, the kernel has the ext2fs module, so i'm at a loss with regards to this issue. any help regarding this would be greatly appreciated, thnx.
