Hello
With -CURRENT from today (and also from yesterday for that matter) I
get the panic "mutex Giant not owned at
/usr/src/sys/nfsclient/nfs_socket.c:461" sometimes (probably 1/3 of
the times) when accessing a NFS mount. The mount was /FreeBSD, and it
panics just by typing "cd /Free<tab>" in a shell. My last good kernel
was from Jan 17. Does this make sense to anyone or is more
information needed?
