Re: [Xen-users] Win8.1 64-bit VGA passthrough - Code 12s and host crashes

[masterfoo@xxxxx <masterfoo@xxxxx>]

I had the host freeze when trying to passthrough a radeon 7750 card to win 8.1, 
under xen 4.4.1. Also using Debian and kernel 3.16 at the time.

Problems mostly gone after upgrading to xen 4.5, passthrough works ok but the 
host still crashes after a few restarts of win8.1 domu. 

For example after applying updates the windows will restart several times, this 
usually leads to computer freezing. Whenever that happens, even the reset 
button won't work, I have to power down the machine.

I wonder if there's a way to fix that?
