[2.1.93] minix FS oops

I get on oops whenever I attempt to run df with a minix filesystem
mounted. The mount command report the minix partition as mounted
but it is not accessible.
The minix filesystem was created within minix 2.0 (on the minix /dev/hd3)
and works fine there, but Linux get an oops on every attempt to use it.
Have I missed something about minix FS or is this a bug?
