Comment # 7 on bug 56139 from 
Alex, would it be possible to print what is going on or if an error occurred in
evergreen_mc_stop()?

I see four things that could be going on:
1- we are not using the right path for CAYMAN -> (ASIC_IS_DCE6(rdev));
2- lock mechanism synced with vblank is not working properly;
3- all the registers should be locked at the same time, then all modified and
finally unlocked together, which is not done with the for loop where we move
through each at a time;
4- we are not setting the right registers.

What do you think?

I can test and investigate 1, 3 and 4. But what about 2?
