Hi Trond,
No, but I will try this now.
Actually, we just saw another similar crash on another machine which is
an NFS client from this server (no nfsd running). Same backtrace, but
this time RAX was "32322e32352e3031", which is obviously ASCII
("22.25.01"), so memory scribbling seems to definitely be happening...
