: The values in the RA & PC are probably accurate & they could indicate
: that something followed a null function pointer.

I would assume it's a kernel function.  I naively assume a long jump to a
null
pointer in user space would result in the crash of the user program (cp in
this
instance) but not a kernel panic.

: Maybe you could provide more details?  Like kldstat output & perhaps

Sure!  I can even provide you with a login to that box if you so desire.
I'll
disable the mount of swap and you can get crash dumps too.

: module?  Are you certain your modules match your kernel?  If they or
: anything else is loaded as a module, can you try compiling everything
: (but osf/1) into your kernel statically?

Everything is static.  I was agressive with the removal of things from my
kernel config, but I don't think I nuked anything something else was
depending
on.  Removing things like FFS_ROOT may have very creepy side effects.  It
has
been running fine up to this point.
