I remember using a 3rd party control panel that used a kind of bisection method to diagnose bad extensions. It would disable one half of your extensions, reboot, and ask if you could reproduce the problem, you answered yes or no, then (depending on your answer) it would disable the other half (or one quarter) and re-enable the first half and so on, narrowing down until the problematic extension was located. I don't remember what it was called! Funny that such a bizarre problem could get so bad people developed sophisticated tools to deal with it. Edit: Ahhh, I think it was Conflict Catcher! Thanks sibling comment!
