Aloha Gordon,

When you say "BSOD on subsequent start-ups," are you saying that on the
boot after AMD driver installation your system BSODs?  How do you manage
to get around that, by simply restarting the host?

What I am referring to is the following:

1) Boot up host.
2) Start up domU - works every time now with <= 2GB of RAM (any more 3GB sometimes works. 4GB+ hardly ever gets to the login screen)
3) Shut down domU
4) At this stage, starting up the domU usually works. Maybe half of the time it BSODs or loses the USB devices (they show up with a yellow exclamation mark in device manager - ejecting them doesn't help). 5) Repeat from 3) At this point things never get past a BSOD and the only way to get the domU working again is to reboot the host.

This should now probably become a couple of new threads:
1) VGA passthrough BSOD-ing with a domU with more than 2GB of RAM
2) domU reboots cause USB controllers to become unavailable
