HPFS filesystem problems

I compiled 2.1.46 and when hpfs was selected, it would not compile.
Now, I can compile with hpfs, it mounts, but it gives an oops when
trying to get a directory listing. I don't know who specifically is
working on this part, but here is what info I can get about what is
happening. It happens the same every time. Let me know if there is more
info required and how to get it and I will get it.

The HPFS drive is mounted at /os2.
I looked up the EIP code and found the following (I just picked the
closest, as the doc said):

c0134248--> bmap
c013426c--> inode_init
c0134284--> fs_may_mount
c013428c--> fs_may_umount
c0134294--> fs_may_remount
c013429c--> dfree
c013429c--> gcc compiled.
c01342c8--> dput

Here is what I did and what I got in return:

cd /os2
