[QUOTE="plyle, post: 1898871, member: 409896"] Thanks for your response and as I continue to test options, I'm learning more about the crashes. 1 ) I would love to find out what the AICOPHY function call means. It always crashes with this function call but I can't find any reference to the call. 2 ) If I use the Mac charger hooked to the USB-C port, it doesn't crash. The crashes have always occurred with a 3rd party PD 3.0 charger and 100 watt PD 3.0 USB-C cable. Reading I've learned that the PD protocall the Mac charger supports is 3.1 which is newer than 3.0. While I agree that I should be using an Apple charger, USB-C & PD are a standardized protocol and It's difficult to believe that 3rd party chargers would fail. 3) I feel that it is related to the anti-aging switch and the charging routines. If I turn it off it doesn't usually panic. I'm still trying to come up with a defined list of conditions which cause the crash but for now it all points to using 3rd party USB-C 3.0 PD chargers. I've gotten a small 60 watt PD charger for my laptop case and will try charging with that one to see if I can make the MBP crash. While I appreciate the fact that Monterey has smart charging, the fact is the battery is not easily user changeable like older laptops. My Lenovo ThinkPad uses options that allow you to set the maximum charge level and it will turn off charging and has worked well also. For the first time I have a full featured laptop which will easily last all day even starting with a charge level around 80% and for me that is much appreciated. 4) After posting my tale of woe on a number of Mac related forums, I've found several people with the same issue. One person said running the 12.1 beta solved the problem. It will be interesting to see if the issue goes away when 12.1 is formally released. 5) Thanks to everyone who has offered suggestions to resolve the problem. In my day job I often have to troubleshoot complex control systems and have found this issue interesting to say the least. [/QUOTE]
