[Bug 66963] r600: linux 3.11RC isn't booting with radeon.dpm=1 option in grub

https://bugs.freedesktop.org/show_bug.cgi?id=66963

--- Comment #26 from Sergey orbitgray@ukr.net --- Created attachment 83321 --> https://bugs.freedesktop.org/attachment.cgi?id=83321&action=edit dmesg for patches from comment 23 and 24

Here are results:

With patch from comment 23: 1 hang in 5 boots, good work (no delays in Xorg). Hang was on first try after hot reset, and was never seen afterwards.

With patch from comment 24: 2 hang in 4 boots, huge delays in Xorg (same as was before)

With patch from comment 25: never got booted after 10 iterations. (behavior might be similar as it was without this patch, but less luck during testing)
