Default Bug#658980: general: The watchdog died unexpectedly.

Package: general
Severity: critical
Justification: breaks unrelated software

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

* What led up to the situation?
I was watching a movie online, using VLC media player and it just stopped playing. I lost my internet connectivity, so I checked with my mobile phone and figured the internet connection is just fine. The debian was completely cut off of the internet. Ping couldn't resolve any host, ifconfig reported nothing unusual, /etc/init.d/networking restart didn't help, so I checked in /var/log/messages and found this:

* What exactly did you do (or not do) that was effective (or
ineffective)?
I described above. After that, I restarted my home router and then I was able to ping it and log into it over the web interface, but nothing after the router could be accessed, until the reboot.
* What was the outcome of this action?
I had to reboot the situation, because there was no other way to make my machine connect to the internet again.
* What outcome did you expect instead?
The internet to work

This is quite obviously a kernel backtrace. I have no idea why you reported
this against a user level software package. Thus I reassign it to the kernel I
*think* you might be running. Also I changed the severity although I don't
really know what the right serity for a kernel problem like this is.
