hi,

got the following panic on my ss5 running a kernel compiled form
anoncvs current-sources cvs'ed last night around 2:14 MET. (userland
compiled on Aug. 3) The system was doing a "make UPDATE=1 build" w/
sources nfs-mounted from an E450 running Solaris2.6 (called
bambam). On top of this nfs-mount /usr/src is union-mounted, on top of
this /usr/lsrc - somethind like: 

bambam:/BSD             /BSD    nfs     rw,bg,intr      0 0
/BSD/NetBSD/NetBSD-current/src /usr/src union   ro,noauto       0 0
/usr/lsrc               /usr/src        union   rw,noauto       0 0

hm, the union-mount of /usr/src should probably be a null-mount?!

Maybe this is not the most resonable way of doing things, it should
not panic the machine. At least I think so... ;-)

Before I forget:
    - The kernel has softdep compiled in, but the it's not used yet.  
    - /usr, /usr/src, /usr/lsrc and /usr/obj are all on the same partition.
    - The ss5 has 128MB ram

Any ideas anyone? Perhaps a bad SIMM???

    -kurt
