The basic calls are 0160:fixme:powermgnt:PowerCreateRequest (000000000011F280): stub 0160:fixme:powermgnt:PowerSetRequest (00000000CAFECAFE, 0): stub 0160:fixme:powermgnt:PowerClearRequest (00000000CAFECAFE, 0): stub 0160:fixme:process:CloseHandle XXXXXXX: Free 0xcafecafe
The CloseHandle call was causing a crash. I added check (Handle == 0xCAFECAFE return TRUE) in CloseHandle and the crash disappeared.
It was suggested that since CloseHandle is required, just to create an event or something simple so the handle will be through the calls.
If you are attempting to reproduce the crash. Open Windows steam Click on a game to view it's content. Or Your Profile/Library/ Sometimes isn't crash straight away.
