There are two things to suggest here. Atfer a panic occurs you can get a
stack backstrace from the kernel with by typing trace at the kshell
prompt. IIRC These kernels did have some problems with interrupt masking
which made them unreliable occaisionally.

The other is to try the much later voyager kernels #5328 which are support 
StrongARM and AR6/7 cores in the same kernel and contain a lot of bug
fixes. I have found kernels of this generation very stable and a bit
quicker than some of the older ones.
