I have had the EXACT same problem (on a 1Ghz AI PowerBook) since Tiger shipped. A few days ago I think I figured out the problem (I've had access to another machine for debugging, so it wasn't a priority). I found that if I removed the Airport card, no more auto- shutdowns when the attach the debugger. No problems for the past few days. What gets me is that this problem even exists. There has to be a few Apple devs debugging on PowerBooks with Airport cards installed. Panther and Jaguar were and still are fine with the Airport card installed. I'm wondering if anyone has seen the kind of problems I am experiencing debugging my kext with gdb. I'm following the same basic process for debugging as the Hello Debugger example: http://developer.apple.com/documentation/Darwin/Conceptual/ KEXTConcept/KEXT ConceptDebugger/hello_debugger.html If I attempt to make the PB the target and the Tower the dev machine, at the point in gdb when I enter "continue" I immediately get a message in the Terminal that says: I haven't set any breakpoints nor does my kext have any code to drop into the debugger. Just selecting continue after attaching shouldn't get tangled with my kext as far as I know, so I don't what is dropping into the debugger or causing the machine to shut down. If I go the other direction and make the PB the dev machine and the tower the target, I don't see this happen, but when I try to list any sources all I get is a line number and the path to the source. It's completely useless. The last time I did kext debugging was under Panther. I didn't have problems like this. This email sent to site_archiver@lists.apple.com
