Hi,

> Cannot dump. No dump device defined.

At least I know what this means. If you don't define a dump device, the 
swapper can't dump the corrupted swap data anywhere so you can analyse 
it later. Rather than explain here I recommend you, and everyone else in 
fact, read and digest these tutorials.

They're a little out of date but still work perfectly well. I managed to 
help Ben Close stomp a bug in the wpi driver after reading these 
tutorials. All hail Michael Lucas. :P
