Hi rick, i tried to start a LXC container on Debian Squeeze from my freebsd ZFS+NFSv4 server and i also have a deadlock on nfsd (vfs.lookup_shared=0). Deadlock procs each time i launch a squeeze container, it seems (3 tries, 3 fails). 921 - D 0:00.02 nfsd: server (nfsd) Here is the procstat -kk PID TID COMM TDNAME KSTACK 921 100538 nfsd nfsd: master
