I did an update today to whatever is the latest on testing and now my 1998 PowerBook G3 Series (Wallstreet / PDQ) hangs during boot at the "initializing laptop mode" line.
Actually it hung at the "deactivating laptop mode" line when I powered it down a few hours ago, but it was a somewhat stressful situation -- I was turning off equipment to try to discover the location of some smoke. (It turns out the smoke was coming from a flatbed scanner.) So I had to reset the PowerBook to get it to power off. NOW I can't boot back into linux at all so I need to figure out how to do a rescue boot on an oldworld .... Anyone else having trouble with laptop mode?
