  I think what is happening here is that Windows is enabling legacy 
interrupts on the device, and that happens to be on the same shared IRQ 
line that the ATA controller is on, resulting in spurious interrupts.

  The dmesg for the system may be able to confirm this, since it should 
list the legacy IRQs that have been assigned.

  bhyve PCI passthru relies not only on the device supporting MSI/MSI-x 
interrupts, but the guest using those.

later,

Peter.
