Hi,

I have experienced an error message about stale NFS files when looking 
into a directory.

ls -la manpages-dev.md5sums
ls: cannot access manpages-dev.md5sums: Stale NFS file handle
root@c3po:/media/revo/@/var/lib/dpkg/info# rm manpages-dev.md5sums
rm: cannot remove ‘manpages-dev.md5sums’: Stale NFS file handle

Running btrfsck I see:

btrfsck --repair /dev/revo/root

Btrfs v0.20-rc1

Scrubbing and btrfsck do not fix the issue.

I tried with 3.9.0rc6 and otherwise with 3.8.8 (and 3.8.0-19-generic 
#29-Ubuntu)

I have uploaded the btrfs-image to
http://ubuntuone.com/3tIHcUdfGEdmrSY1oxGCL3

The drive is an 64GB crucial M4 SSD. Smartinfo can be found here:

Any help appreciated.

Rgds,
Chris
