I am looking for hints to debug a driver I am working on. I get a page fault when running the driver intensively. The stack trace from the kernel dump only goes up to a free command which I suspect is being called from my driver. No matter what I do I cannot get a more "complete" stack trace. kgdb says something about the stack being corrupt when I do a backtrace/stack trace. Is there anything else I could use to help me pinpoint where I am going wrong? I have tried memguard but it has given me no information. Maybe I am using it incorrectly. Riaan
