Okay, I've installed and booted the 3.3.0rc6 kernel. Since the problem is intermittent, I'll wait a few days before reporting back.
There was a DKMS error message when installing the test kernel, and I'm unable to start one of my VirtualBox VMs when the host is running the 3.3.0 kernel.

That might limit my testing some, but I'll see what I can do. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/907168 Title: [ 3.0.0-14 regression ] Radeon 3200 GPU blank screen on resume To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/907168/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
