I'm primarily interested in getting a kernel backtrace from my kernel

extension. I'm porting a library that provides various services to

other kernel extensions we develop. One of these services is to capture

a backtrace. For example, we may capture a backtrace when a kernel

extension detects an error in order to facilitate the debugging of that

error condition. As another example, we may capture a backtrace when a

kernel extension acquires a resource in order to later determine who

acquired that resource if the resource is leaked.

Sounds like you want something like the MallocStackLogging env var (and his friends), but at kernel level. Maybe looking at the code for that would be insightful, though I'm sure it wouldn't work without change at kernel level. It sure would be nice if the OS provided something like that 'for free' at kernel level :) -- ____________________________________________________________ Sean McBride, B.
