Is the target filesystem ext3?  There's some bug that causes this
behavior.  I could very easily reproduce it by copying lots of data (I
was trying to move /usr/ to its own disk).  I was completely unable to
get any help from the ext3 devel list or the sparc kernel list, or the
main kernel dev list, so it's probably still there.

See if you get the crash when the target fs is ext2.  And, as Ben
already said, use ksymoops to give some meaning to that code dump you
have.
