[ltp] diagnosing a freeze on T60p with ubuntu hardy

[Phil Shotton]

What is your graphics card, and what are you doing at the time of the 
freeze?
I can get exactly the same symptoms (frozen system but with stuttering 
sound) pretty reproducibly by playing a video in mplayer using the gl2 
video output and selecting full-screen. This is with an ATI Mobility 
FireGL V5250.
Provided I don't play video then 99% of the time it's fine.
