Unfortunately, those patches did not help. The GPU hang still occurs (I tested
without setting radeon.runpm=0).
I applied the patches against 3.13.6 kernel

Setting radeon.runpm=0 helped. Suspend, resume work correctly now.
Which kernel version should I apply the patches to and test with? Latest git
commit (3.14-git), or stable 3.13.x kernel code?

Confirmed:
This commit : 10ebc0bc09344ab6310309169efc73dfe6c23d72

Still have 2-3 more revisions to test.
I suspect it is most likely this commit:

I've started using git bisect to find the bad commit(s)
I am bisecting between 3.12 and 3.13 (as tagged)

Unfortunately disabling dpm did not help.
I set radeon.dpm=0 and booted the Linux 3.13.5 kernel, and the same problems
still occurred. Will attach dmesg output shortly.
I will try bisecting.

Compiled and installed Linux 3.12.12 kernel. No GPU hang problems occur for
suspend and resume. Works fine (other than the fact that the laptop's display
connected through LVDS is blank).
I will post the dmesg out
