I put the 0x2000 flag in there for now. Haven't a clue how to tell if it needed the 0x6000 flag or not. Thus far, the 0x2000 flag appears to be doing okay. This time for testing I attempted to throw a LOT more curve balls at the system. Forced sleep mode in the middle of downloading a web page. Sometimes woke it up without an ethernet connection. Powered up with external mouse, sleep, pull mouse, wake. Various combinations of that one. Tried forcing sleep in the middle of starting up a couple of different apps. Also while in the midst of closing them down Tested with and without external power for all of the above. Cycled sleep mode enough to get it peddled across town! In short, all the kinds of nasty things you generally wouldn't want to do under normal circumstances. For each and every one, the system came back to life without issue. I still haven't been able to determine a specific trigger for the lock ups though. I ran more extensive testing than previously, but for all that I did I honestly don't know if I tested what would show this fixed or not. This is a pretty serious stablity issue here in my mind. If I find anything new or interesting on this I'll be sure to update the list on it. I know I'd appreciate hearing anything others might find concerning this.
