Hmm, can she collect output of 'udevadm monitor -p' at the time you
assign the adapter to the VM? Also, do you have any udev rules that is
specific to cxgb? Or any other custom udev rules?

Also, we only suppress the modalias string on driver unbind, could it
be that for you module loading is happening when driver is bound to
the device? Actually, as far as I can see, you share PCI IDs between
cxgb4 and cxgb4vf drivers, so they have similar modalias entries. How
do you normally decide what driver is to be loaded for a given device?

Thanks.
