--- Comment #8 from kartik <kapoorkkartik at gmail.com> ---
First I Have explicitly set radeon.dpm = 1 which did not solve the problem.
Then I have explicitly set radeon.dpm = 1 and forced High performance mode. It
did not solve the problem either.

Then finally I did not explicitly set radeon.dpm = 1 but it was enabled
implicitly and i forced High performance mode and no more currupton.

Curruption is gone after forcing high performance mode in dpm or disabling dpm
with radeon.dpm = 0 . 

Please look into this.
