Hi everybody, and sorry if i have posted this question in wrong forum, i'm a new commer only. Actually i faced the problem when doing troubleshooting the drivers conflict case. From the dump file analysis with Win Debugger i know there was a kernel mode program conflict ( most properly driver conflict ) at specific memory region ( to simplize it lets call it region A ). So if the driver conflict occur at memory region A, it mean that at the same time there should be at least 2 device driver ( or in general 2 kernel-mode program ) were writing to this memory region ? 1st : Is this possible for me to know which driver is writing to this region at this specific time ? If yes, which tools i have to use ? 2nd : If the 1st option is not possible, so is there something like lookup table in which all the driver details ( including which memory region its going to operate on ) are listed ? Because from my experience, Linux does offer a table like this. 3rd : If both 2 options above are not possible, so any expert please can guide me and help me some useful documents regarding this topic. Thank you very much. Your sincerely.
