Is this a regression? Did the driver work properly with an older kernel, etc? Does booting with radeon.runpm=0 on the kernel command line in grub help?

(In reply to comment #5) > Booting with radeon.runpm=0 helps, but what radeon.runpm do? It disables dynamic powering up/down of the dGPU in your system. Make sure your kernel has this patch: http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f244d8b623dae7a7bc695b0336f67729b95a9736
