--- Comment #60 from Mathias Tillman <master.homer@gmail.com> ---
I've done some further tests with overriding the power state level values as
detailed above, here are my results:
The stock values are
level 0: sclk: 10000, mclk: 30000, vddc: 950, vddci: 950
level 1: sclk: 77500, mclk: 105000, vddc: 1100 vddci: 1150
level 2: sclk: 90000, mclk: 105000, vddc: 1175, vddci: 1150
sclk, vddc and vddci were all at their stock values for all power levels during
my tests.
I changed mclk on power level 2 to the values below (OK means that it does not
get stuck in the highest power level):
95000 = OK
100000 = OK
104000 = OK
105000 = NOT OK
110000 = NOT OK
So as you can see it gets stuck when the mclk value is 10500 or higher, but why
that is I really have no idea. Could it be a firmware or VBIOS problem?
