Fedora Hangs on Laptop

[Dave Cross]

I'm running Fedora 9 on a Dell XPS M1330 laptop. I'm using one of the
earliest F9 kernel (2.6.25-14.fc9.i686.PAE) because I've been unable
to get a wireless connection with any later kernel that I've tried.

But I'm having huge problems with this kernel too. At random times the
machine just freezes completely. The capslock and num-lock buttons
flash on and off but the only way out of it seems to be to turn the
system off and restart. Sometimes it can be an hour or so before the
problems occurs, but more often it's a few minutes. This obviously
makes the system pretty much unusable. I can use the system for as
long as Iike when I boot it into Vista.

Has anyone else seen this behaviour? Or do you have any suggestions on
how I can help to investigate the problem?

Thanks,

Dave...
