signal 4 is SIGILL. Just a guess but do you have a cputable entry for
440GR rev B in your arch/powerpc/kernel/cputable.c? If you don't then
I think the default kernel settings will result in the wrong cacheline
size being used, which leads to userspace often dying with illegal
instruction traps.
(I don't see any 440GR entries in cputable.c, neither rev A nor rev B,
in the upstream kernel so I'm assuming you're patching your kernel
somehow. So checking that your patch covers rev B would be the first
thing to do)
