Hello folks.  Well, I struggle on with this Sparc 5 that won't stay 
running for more than a few hours.  I've tried the NetBSD-1.4.2_ALPHA
kernel to no avail.  However, I've captured a traceback through a script
session, and filled in the appropriate function names in the trace.  It
appears that I'm suffering from a double panic, once in the lockmgr, but
another caused by a call to memfault_sun4m from ffs_alloccg.  This probably
isn't a call, but rather some sort of harddware trap.  Might anyone be able
to shed light on what's going on here?  Here's the traceback, along with
the dmesg output for the kernel.  If anyone cares, I also have the kernel
core image from the panic session, which I'd be happy to provide for
analysis.
-thanks
-Brian
