What Tomasz said, and if that doesn't help use bootchart and upload
the chart somewhere so I can see what's going on. Thanks,
I'll give it a try. It's my laptop so I don't keep anything I care
about on it. It's also my work laptop (dual boots XP which I'm using
now). I may sneak in a reboot at work to make the chart, otherwise it
will be tonight.
