Laptop locks up

[Bart Silverstrim]

I have a friend that is running 8.04 on a Dell Precision M2300. He tried 
using 8.10 on it, but said that it would lock up tight at random time 
intervals. He said the logs were empty of errors from the time of the 
freezes, pointer locked, keyboard, etc...nothing responded. Not even 
connecting remotely from another system into the laptop would work, so 
even the network stack stopped responding.

He reverted to 8.04 and said it's okay with him because it works fine 
for his needs, but did anyone else run into behavior like this in moving 
8.04 to 8.10?
