SubjectRe: Hard lock on 2.6-test9 (More Info)
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,
