** Description changed: My machine experiences random and complete system lock-ups when running the Ubuntu kernel with the radeon.dpm=1 boot option set. This does not occur on the mainline build nor the latest upstream kernel, so it must be related to one of Ubuntu's patches. The system is left completely unresponsive. There are no error messages, no logs created and no keyboard indicators (flashing lights). The system - is dead and need to be hard-powered off. As it appears to be completely + is dead and needs to be hard-powered off. As it appears to be completely random I have no idea how to trigger it, but if anyone has any ideas then I am willing to give it a go. 01:05.0 VGA compatible controller: Advanced Micro Devices, Inc.
