IIRC some drivers were very unhappy with this, IIRC something about interrupts waking a processor that then started a transfer, while something running on the other was already waiting for a transfer to complete. For some (virtual) hardware combinations it worked smoothly but others were very unreliable. We just switched to the single professor HAL as that still performed as well as the older CPUs when virtualizing on newer kit and was much more reliably stable.
