Package: nfs-kernel-server
Version: 1:1.2.6-4
Severity: important

Dear Maintainer,
*** Please consider answering these questions, where appropriate ***

   * What led up to the situation?
I am using Debian wheezy on my QNAP TS-221 for private data storage. The NAS
ist equipped with 2 3TB WD RED drives using linux-MD raid 1. The home
partition is exported via nfs and mounted by two linux boxes (wheeezy).  
Every 6 hours rsnapshot writes backups to /home.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
After coming backup from holidays I installed some security updates,   
rebooted the qnap and manually started rsnaphot for a new
backup. Then the backup stopped and the qnap-box showed a kernel-oops but
was still available via SSH.

   * What was the outcome of this action?
The NAS box was still available via SSH but NFS was not working anymore.
dmesg showed the following:

   * What was the outcome of this action?
The qnap was rebooted and NFS was working again. I tried the backup again but
the problem with the kernel-oops persists.

   * What outcome did you expect instead?
The qnap has showed this problem before and I was hoping it was temporary
and would hopefully go away by itself... ;-)

Could you please provide me with some information how to circumvent this
problem or how to help removing this problem? Could this even be a
hardware problem? How could I possibly find out?
