--- Comment #5 from Alex Deucher agd5f@yahoo.com --- (In reply to comment #4)
it didnt solve the bug with my RV730 chip, but when I commented out the whole if block it did work so maybe my chip is from before chedar
Your chip is before cedar so the patch prevents that block from executing on your chip, the same as commenting out the entire block. Are you sure you tested the right kernel?
