Hi Steven, sorry, I don't think I know anymore how mmiotrace works. Surely the kernel has changed in those more than 10 years since I last looked at it. If I'm still listed as a contact for mmiotrace somewhere, maybe it would be best to drop me? I don't mind the emails, it's nice to see people hit or touch it, but I'm afraid I can't help. Thanks, pq
