Currently on airlieds drm-radeon-testing, but the same happens with mainline. I
did an bisect run before, i will attach the log. However just reverting the
commit didnt help, so i dont think the log is right.

I also think that new pm-code is not to blame, i guess that activativing the
old code on boot time with the dynpm option led to an longer initializing time
of the chipset. I am not an programmer, but looked at the code of r420.c, the
old code kicked in after the initialize of the clocks, maybe more time is
needed there ? But maybe i am wrong, i added about 50 printks after
radeon_get_clock_info(rdev->ddev); sometimes it works no, sometimes not.

I had the issue since the beginning of radeon-kms, it started working after i
used the dynpm option at boot time, never without.
