I've had this happen every time I've connected an Apple USB Keyboard (with MM attached) to my new MBP 2.0 GHz on 10.4.6.

Basically, when I get my (sleeping) MBP out of its bag, I hook it up to DVI, plug in a USB Keyboard and then AC power to use it in closed-lid mode. That works with any other PowerBook I have and according to Apple's documentation it works just the same with the MBP. Unfortunately when I plug in AC power I hear the boot chime and see the MBP reboot the OS. When it's done it claims Mac OS X had to restart because it crashed.

This is the entry in panic.log:

Does anybody understand what is happening? Has anybody seen his happen too? Is it a 10.4.6 bug or does it disappear with the firmware update? Workarounds?

I continued to do some trouble-shooting on my own.

I noticed that it wasn't the USB connection causing the crash, but actually just waking from sleep. I didn't know why. I figured it always worked on my PBs, so it might have to do with Intel or Rosetta. I checked and saw that the only Rosetta app that was always running was MKConsole. I then saw that not running MKConsole would prevent the crashes from happening upon waking the MBP. To be sure it was MKConsole and not Rosetta emulation per se, I tried it with another PPC app under Rosetta emulation: Word 2004. No crashes.

So I guess the crashes were really being caused by MKConsole itself. There's no UB port of the app. I've stopped running it and informed the developer.
