linuxppc kernel crash -- suggestions?

[Geoff Wyche]

Hello all,

I've got a linuxppc_2_4 (rather current) kernel running on an MPC860T with
16MB ram.

While attempting to boot with a rootfs via NFS, I received this oops:

Oops: kernel access of bad area, sig: 11

C01297A0 C000259C C0004E50
Kernel panic: Attempted to kill init!

I've tracked down some of the backtrace:

(crash) <- kmem_cache_grow <- kmem_cache_free \
<- kmalloc <- proc_create <- register_proc_table <- uid_cache_init <-
do_basic_setup <- init

What typical problem would cause this... Is this what happens when the
kernel runs out of memory during init?
