Were you able to find any config options that don't look good to you? Similarly, I have a nagging but annoying problem where my laptop will occasionally hard deadlock when I plug the power back in while it was running on batteries. I've had this problem for quite a while too, across kernel version, and interestingly enough, restarting acpid from cron may have been a workaround in the past, and of course I can't reproduce that one at will either, so it's hard to get a debugging setup when it happens. This actually started happening at the same time that for some dumb reason, acpid stopped logging to /var/log/acpid more than a year ago :( I just upgraded to 2.6.28.4 so we'll see what happens, but if you have recommendations on kernel options, debugging, or other ideas, I'm all ears. (like can I debug on usb serial, or do I need real serial?)
