Excellent. You can help me track it down then. Can you look at
radeon_pm.c, function

radeon_pm_enable_dynamic_mode()

The code for your chip is after the comment "/* Others */" (the M7 is an
RV200 chip). Can you comment out the various bits in there and see if
you can locate which one is causing your problem ?

Thanks in advance !

Ben.
