Hi Dan, I manually walked through the driver code and spotted the issue. But this morning I was able to get an extra module to verify my patch on hardware. I tested the following patterns using two identical modules, and checked the creation/destruction/ref_cnt of wm_event: - insert module A, remove A - insert A, insert B, remove A, remove B - insert A, insert B, remove B, remove A - insert A, insert B, remove A, remove B - insert A, insert B, remove B, insert B, remove B, remove A Thanks, Ben On Thu, Aug 9, 2012 at 11:28 PM, Dan Carpenter <dan.carpenter@xxxxxxxxxx> wrote: > Ben, I'm confused.
