Hi,

I was trying to chase down a theory that my desktop machine (a core i7)
is running warm (the fan sounds like it's at full speed all the time,
and I think it's not always acted this way -- hence the theory).

powertop is never showing it spending any time in C3...

I compiled a kernel without USB/sound/radeon, and ran without X. I was
able to get the wakeups/sec down below 20, but no time is spent in C3.

sysfs looks to agree with powertop here (time = 0 on C3):
/sys/devices/system/cpu/cpu0/cpuidle/state0/desc: CPUIDLE CORE POLL IDLE

/sys/devices/system/cpu/cpu0/cpuidle/state2/time: 873440787
/sys/devices/system/cpu/cpu0/cpuidle/state2/usage: 239038
/sys/devices/system/cpu/cpu0/cpuidle/state3/desc: ACPI FFH INTEL MWAIT 0x20
/sys/devices/system/cpu/cpu0/cpuidle/state3/latency: 17
/sys/devices/system/cpu/cpu0/cpuidle/state3/name: C3
/sys/devices/system/cpu/cpu0/cpuidle/state3/power: 350
/sys/devices/system/cpu/cpu0/cpuidle/state3/time: 0
/sys/devices/system/cpu/cpu0/cpuidle/state3/usage: 0

This may be a complete red herring, but I added some printk logic to
acpi_idle_bm_check(), and it is getting called often, but bm_status is
always 1. [I infer from this that the idle logic is trying to go into
C3, but this check is stopping it... Unless I misread something.]

Is this expected behavior or is this a legitimate problem?

How might I investigate this further?

Attaching dmesg, /proc/cpuinfo, powertop -d output.

Thanks,
Jeff Garrett
