msm 7200A has: 1 apps processor, 1 modem
All the android code runs on the apps processor, so its a single core
system to the OS.

Applications:
Once all apps have released their wakelocks
App Framework:
Power manager service decides to suspend the device (if the user turns

Do you know if its a kernel reboot or a framework restart?
If its the kernel crashing you can get a persistent logs found:
For Nexus One:
You can check /proc/last_kmsg
On Droid:
/data/dontpanic/apanic_console
Make sure to check the timestamp of the file created or in the dmesg,
sometimes if the
On Droid we use the OMAP watchdog. I've found it useful to catch lockups in
the kernel suspend / resume path for drivers.

Maybe try task_tgid_nr(current) ?

What phone did you buy? If you're talking about the Nexus One the
userspace governor is already compiled into the kernel. Otherwise
you'll probably have to recompile the kernel with the userspace
governor.
We do DVFS using the ondemand governor currently.
To enable userspace governor:
adb shell e

What kernel are you on? Does this happen with you have a very large
number of wakelocks in the system?

Currently we don't have CONFIG_FUSE_FS enabled so this is possible
unless you run a custom kernel. You will also have to setup the proper
permissions on the mount point.

That message indicates that the device is going into sleep. State 0 is
on, I'm not sure what state 2 is, as android should only use states 0
and 3 (3 is suspend). This is being triggered by userspace so most
likely the framework is telling the kernel to sleep (probably screen
timeout).
What kernel
you should look at http://android.git.kernel.org/
check out the common tree, and the msm / omap tree if you want device specifics

You are certain this is a valid speed you are writing?
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
Also make sure the speed you are writing to are within the
scaling_min_freq / scaling_max_freq limits.

The actual power consumption of the device should lower if you do not
hold the wakelock, what you call (power save mode).
The reason why you see a sudden spike in the /proc/cpuload is because
when you wake up the device the cpuload timers are queued up so
CALC_LOAD is called muitple times for the
ot;Fix 2.6.29 build".
