I've got a need for a kernel driver to go to sleep for a number of MS and then be awoken by an interrupt. Timing is critical, so I can't just tsleep and get rescheduled later, and I don't have hardware of my own to generate the interrupt. Therfore, I need to get a free CTC register, program it up, and have it generate an interrupt that I can service in the device driver. Does anyone have any suggestions/ideas/help/pointers on how to do this. I've never done this kind of stuff with PC hardware before, so I don't even know where to start looking. Thanks, Paul
