--- Comment #14 from Adam Honse <calcprogrammer1 at gmail.com> ---
I'm marking this as reopened.  Still having the problem with kernel 3.12-rc4
which has that patch.  Starting the machine with radeon.dpm=1 works fine until
I start Xorg (sudo start gdm on Ubuntu), then it blank screens and hangs
completely within seconds.  I cannot reliably shut off the dGPU before loading
the Radeon module and trying to shut the dGPU off after loading Radeon but
before starting Xorg results in the turn_off_gpu script hanging at the ACPI
call that is supposed to work for my card when radeon.dpm=1.

One thing I've noticed from reading the bugs related to this is everyone seems
to be using VLIW + VLIW systems.  Mine is VLIW + GCN (r600 + radeonsi) as the
7730M (AMD VERDE) is GCN while the integrated 7660G (AMD ARUBA) is VLIW.  I'm
not sure if this has any effect on the bug or not, but I figured it's worth
mentioning.
