i915 question

[gene heskett]

Greetings;

I have a pair of small machines, ideal for running cnc machinery, that are 
Atom based with i915 video, on Intel D525MW motherboards.

I am having way more than I'd consider normal crashes/lockups/spontaneous 
reboots when closing applications.  These events leave no evidence in the 
logs, and generally consist of the screen going black with a frozen mouse 
cursor about 1 second after closing an app, needing (usually) a reset or 
power cycle to reboot.

I am getting the feeling that I ought to be pointing my finger at the i915 
driver.  Is there any way to hang something on it that would confirm or 
deny that hunch?  Some sort of a watchdog timer perhaps?

Cheers, Gene
