No need. Based on the line that it crashed at, the problem is that with no 
mappings no pv_entry has been allocated. Somehow on your laptop you're able to 
get in to a situation where fictitious pages have been added to the object that 
don't get mapped. This isn't a strange situation in and of itself, but you seem 
to be the only hitting this. 

In any event, the DRM 4.6 port will support AGP in about a week. It will 
probably have bugs, but this one isn't in any of its code paths.

I'm glad your system works a bit better now.
