Hello!
I have the same problem on my HP 9533eg with a AMD Turion tl-60. It is
indifferent how idle the Laptop runs - it doesn't switch into any Powerstate.
uname -r says this: 2.6.24-18-generic
and this is the output from
cat /proc/acpi/processor/CPU0/*
processor id: 0
acpi id: 0
bus mastering control: yes
power management: yes
throttling control: yes
limit interface: yes
active limit: P0:T0
user limit: P0:T0
thermal limit: P0:T0
active state: C0
max_cstate: C8
bus master activity: 00000000
maximum allowed latency: 8000 usec
states:
C1: type[C1] promotion[--] demotion[--] latency[000]

C3: type[C3] promotion[--] demotion[--] latency[020]
usage[00000000] duration[00000000000000000000]
state count: 8
active state: T0
state available: T0 to T7
states:
*T0: 100%
T1: 87%
T2: 75%
T3: 62%
T4: 50%
T5: 37%
T6: 25%
T7: 12%
throttling works perfect with powernowd but my main problem is the
temperature of the cpu. It's always above 60 degrees and under heavy
load it reaches 80 degrees.
