Prevent current thread from being preempted while single-stepping my driver

WINDBG
1

When I debug my driver with single stepping, other threads will preempt current thread and run the buggy codes ahead of current thread, then crashed. Can I stop them all in Kernel mode?

Nope, no way to do that. You have to deal with it. One way is put breakpoints in those threads and debug multiple contexts together.

Thanks doron, This is one of things I dislike in kernel debugging.

User mode debugging is pretty much the same thing if you have more than one active thread. Single stepping in one thread can allow others to execute as well.
