I recently got a kernel panic running a binary under COMPAT_OSF1
emulation.  (It is the Tivoli Tru64 TSM 5.1 client.  I wanted to see
if it would run under NetBSD via OSF1 compatibility mode.)

I don't know if this is something specifically within the COMPAT_OSF1
subsystem, or whether it is just tickling something else within the
NetBSD kernel.  Here is what I have in my logs:

Does anyone have any ideas from the above?  (Has anyone else tried to
run the Tru64 TSM client?)

Cheers,

Paul.
