--- Begin Message ---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: [ 580.132803] Unable to handle kernel NULL pointer dereference at virtual address 00000008 [
