Of course hardware/driver implementation of MSI must be bug free. For example my Geforce 8200 mainboard supports well MSI for onboard SATA, Ethernet and audio. The only device which hangs after minutes of use in MSI mode is Geforce 8200 integrated GPU. I do not know if this is GPU hw failure or Nvidia binary driver is buggy.
