About 2.4.19 kernel(ppckernel.org)boot panic?

[Dross Zhou]

Hello all:
	I try to port linuxppc2.4.19-pre8(from
www.ppckernel.org) to our borad from Rpxlite_config.
But it panic after dump some information.
Before porting 2.4.19 , I have porting 2.4.4(from
denx.de) to my borad and it works well, I have done
same work as what i have done with 2.4.4.
What problem,it says 'kernel access of bad area, sig:
11 '

Here is dump:

Linux/PPC load: console=ttyS0,9600 console=tty0
root=/dev/nfs rw

Just wondering, is your CPU old enough (and an MPC860) to need the CPU6
errata work-arounds?  That oops almost looks like the ones that are seen
when you need the CPU6 errata enabled but don't.
