Hi all,

I got this kernel dump when trying to remove some files.

Now, when I try to access the directory, or any file there I get:

---
[xxx@tyler vbox]$ ls
ls: cannot access machine: Stale NFS file handle
harddisk  machine
[xxx@tyler vbox]$ cd machine
bash: cd: machine: Stale NFS file handle
[xxx@tyler vbox]$ ls -la
ls: cannot access machine: Stale NFS file handle
total 0
drwxrwxr-x 1 root root  30 Dec 22  2010 .
drwxrwxr-x 1 root root 112 Jan 18 16:29 ..
drwxrwxr-x 1 root root 154 Jan 18 16:30 harddisk
d????????? ? ?    ?      ?            ? machine
---

On time: that is a local directory, that's not mounted over NFS at all.

---
My system:
Fedora release 15 (Lovelock)
Linux tyler.xxx 2.6.41.9-1.fc15.i686.PAE #1 SMP Fri Jan 13 16:35:57 UTC
2012 i686 i686 i386 GNU/Linux

Btrfs mount over raid0

[xxx@tyler vbox]$ cat /proc/mdstat
Personalities : [raid0]
md0 : active raid0 sdb1[0] sdc1[1]
      312573952 blocks super 1.2 512k chunks

unused devices: <none>
[xxx@tyler vbox]$ mount
[cut]
/dev/md0 on /installed/utils type btrfs (rw,relatime)
[cut]
---


Hope it could be helpful to deploy.

Best regards,
Edilson
