Hi,
I have done some testing on a custom board. it uses uart2
I also see serial hang issues here. I have a minimum defconfig with
only i2c enabled. no cpuidle/cpufreq.
This is what i try to do -
# echo -n mem /sys/power/state
I wait for a min and try to wakeup - It works.
If i
I wait for a min and try to wakeup - It works.
If i wait a little longer before waking it up say, 3 or 4 minutes.
It does not wakeup.
That is consistent with your memory not being placed into self refresh properly.

Another possibility is that the the memory timings for the custom
board are not set correctly.
Yes this is correct also. For example if the XSR field is wrong in SDRC
registers (exit from self refresh

Just a thought, do you still see these problems when using the CPUfreq
performance governor instead of the ondemand governor?
It could be pointing to some bugs in the switching of operating
points.
Speaking of operating points, is there a reason why cpufreq only goes
to 550MHz? It's

If you look at http://beagleboard.org/hardware it says 600Mhz
multiple times, so I'd expect the board to be running at 600MHz if I
were a customer. If I read the TRM right I can run the cpu at 600MHz
continuously for a few years, which exceeds the lifespan of most
mobile products I have
In fact, you wouldn't even need a custom governor.
To avoid governor picking overdrive OPP:
# echo 55 /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
To allow overdrive:
# echo 60 /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
Sure. Now is someone going to fix up
