Re: Hard lock on 2.6-test9 (More Info)

[Dan Creswell <dan@dcrdev.demon.co.uk>]

Thanks for the advice Linus - I'll give that a go.

As an aside, I've tried both the nvidia drivers and the out-of-the-box 
Xfree ones with the same results (2.4 stable, 2.6 not).

I'll get back to the list with more info once I've done the testing.

Thanks again for your time,

Dan.
