:Hi,

:With a kernel built from -current cvsup'd at Sun Aug 22 04:03:19 BST 1999,
:I got the following panic doing make -j8 world with /usr/src via NFS and
:/usr/obj local:
:
:Panic: free vnode isn't
:mp_lock = 00000001; cpuid = 0; lapic.id = 00000000

This is the second person with a crash in nfs_lookup. No major changes
have been made to NFS yet -- my patch set is still uncommitted. I can
only conclude that something else someone has done has broken something.
With my patchset and the latest current, I am able to do buildworlds
in a loop forever on an SMP box using precisely that setup: /usr/src
via NFS, /usr/obj local (and also /usr/obj/ via VN).
At this instant my patch set will not patch cleanly due to some
inappropriate commits made last night which I am trying to resolve.
(However, these commits are probably not responsible for this particular
problem since you indicate an early sunday morning image).
I recommend waiting a few days, hopefully this mess will be straightened
out by then and we can put everyone on the same page again. I can't
update my patch until the mess that was committed last night has been
backed out.
