I suspect it would have been this: xfs_iget_core: ambiguous vns: vp/0x ..... but it would be good to confirm it. This was supposed to be a dead code path which there was no longer a route to, it is possible something in the NFS interface in 2.6 has changed to cause this though. Basically a race between two threads looking up the same inode, xfs has it cached already and two threads raced to setup the mapping from the linux inode. The use of iget_locked when looking up new inodes is supposed to protect against just this condition. Steve
