Hi! Some time ago already, we got graphics card pci passthrough working on a friend's computer, an ASRock Z68 Extreme4 Gen3 based PC with an Intel i7-2600, running on a Linux 3.2 kernel, with two Gigabyte GV-R677SL-1GD (AMD Radeon HD 6770) graphics cards in CrossFireX mode. To get things to work

(please CC, not on the list) Hi all, Fedora 10 randomly hangs for me when run under KVM, whereas (unpatched) F9 works fine. When this happens, kvm_stat shows that the VM is seeing 1000 IRQ exits per second, but nothing else seems to happen. The latest F9 update kernel seems to be bust as well.
