[coyote]

Affects: linux-source-2.6.15 kernel-image-2.6.15-18-386-di (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
After installing Dapper, my system freezes after a random time (somewhere between 2min and 30min). My hardware has always worked "flawlessly" in warty, hoary and breezy, but the freeze has always taken place in any version of Dapper. 
If I use the standard nv driver and delete the watchdog modules, then the system doesn't freeze anymore, but it kills my internet-connection with rebooting as the only answer.
