I pulled r4347 from SVN and built it... I have a Dell M1210 (Core 2 Duo intel), and tried a few things, all with a debian Etch AMD64 guest: 1) chmod'ing /dev/kvm and starting guest as local user 2) starting guest as root 3) starting guest, closing it, then suspend/resuming without unloading the modules. ... then suspending/resuming the laptop. Previously, I could suspend/resume with the modules loaded, but the laptop would hardlock as soon as I tried to start up a guest. This time, in all cases the machine did not come back from suspend, even in case #3 where it used to come back fine. I just get a black screen and no network activity, so I don't have any interesting troubleshooting info. Anything I can do to be of more help?
