Re: VMDirectPath & Adaptec 3805
I've heard from Adaptec that they do not support or even test passthrough. If you're able to get it to work reliably, then don't patch!!

Hello from Adaptec.
Passthrough is not a supported, or tested feature currently. It may work with some controllers/drivers, but as this is not a tested functionality, we can't guarantee that this will work in general, or which controller/driver combinations may work.

This was support case #130805-000034 . I opened it because we were seeing a hang on aac driver load with a 6805 in RHEL5 and 6 after a warm boot of the VM. New firmware, new card, new drivers  all 'round.
