Oops: Kernel access of bad area, sig: 11

[Joakim Tjernlund]

Hi All

I am getting an Oops: Kernel access of bad area, sig: 11 on linuxppc 2.4.8
when I telnet (4-5 sessions will do it) into my board(custom mpc860 board)

If I use Montavistas linux-2.4.2_hhl20 kernel it works(no Oops).

Any idea's?

   Jocke
PS.
   It seems to me that ioremap_base and ioremap_bot isn't initialized
   in mm/init.c for mpc8xx. Bug?
DS.

Below is what I get in my Console:
