It seems Marek has more weight than me about lockups related to VM on Cayman(problem first reported as bug 45018).
Well, we were hoping to get this resolved in time for 9.0, but as it's getting pretty close now, it's probably better to disable it at least for the 9.0 release. The problem is, when it's disabled, there's not much chance of anyone testing it, so it's not likely to ever get properly fixed. Also, SI only supports VM, so we can't disable VM for SI.
Meanwhile, since fixes committed for bug 45018 helped me a lot, I'll gladly keep VM activated to test it. After all, my desktop is now usable now, I've been running for 3 days without any lockup, while I was previously only able to run for a couple of hours before restarting. So, if you have any patches you want to test that could help, ask me.
