AMD Sempron Mobile CPU: No C-States and USB_Suspend - session 2

[fabiannorton]

Hi, i've try it with processor.nocst=1 at the comand line.

But no changes :(

active state:            C1
max_cstate:              C8
bus master activity:     00000000
maximum allowed latency: 8000 usec
states:
    *C1:                  type[C1] promotion[--] demotion[--] 
latency[000] usage[00000000] duration[00000000000000000000]


But i don't understand: the output says: "active state: C1" and 
"max_cstate: C8" - if this don't mean i have upto 8 states?

thanks & regards
Fabian
