Trying to find bugs in linux-source-2.6.17

[Kartik Thakore]

I have a bug for you and I will appreciated if you show me how to fix it


Public bug reported:

Binary package hint: linux-image-2.6.17-10-generic

1. Update from dapper to ubuntu edgy 
2. Install linux-image-generic 
3. At a random time the computer will freeze

You can ctrl-alt-backspace out of it

Here is the output in kern.log and sys.log
