I've had a crash while doing cd /; find . -xdev -print0 | cpio -oumd0 /mnt.
That copy went fine for a while, them I did cd /mnt/tmp; rm -rf * and
shortly after this the machine crashed. The epc is pointing to 800d430c:

this is a branch, so the fault was caused by the following instruction which
was dereferencing a NULL pointer. What makes me more worried about this kind
of crash is I also keep receiving reports about I/O errors and data corruption
from users of the 32-bit kernel while copying from one disk to another
physical disk, so exactly what also happened here.
Ideas?
