Based on your console logs, I see that the working case uses UDP to contact the server's mountd, but the failing case uses TCP. You can try explicitly specifying "proto=udp" to force the use of UDP, to test this theory. Meanwhile, the patch description explicitly states that the default mount option settings have changed. Does it make sense to change the default behavior of NFSROOT mounts to use UDP again? I don't see another way to make this process more reliable across NIC initialization. If this is considered a regression, we can make a patch for 2.6.38-rc and 2.6.37. > Signed-off-by: Chuck Lever <chuck.lever@...cle.com> > Signed-off-by: Trond Myklebust <Trond.Myklebust@...app.com> > > Here's the boot console logs from both the good and bad cases with NFS > and RPC debug enabled.
