Comment 29 for bug 1653162

As far as I know, this is still a current issue. It has nothing to do with Ubuntu, it's a mainline kernel problem. I was working with someone earlier this year and after tracing it to a specific commit (I believe the same one that added "4k" sector support), I was sent somewhere else and kinda dropped it there. I was working on a customer's PC that was finished and needed to be returned. I have since bought a CERC card that it an exact match and may be able to help more if needed. I looked over the code a bit and there were quite a number of changes made to the module at the time to use a whole new set of functions :(. It acts to me like an interrupt timing/sync issue, but the last time I dealt with that was an ISA interrupt sharing methodology in 1990.
