Hi,

On OMAP3 pandora, system suspend stops working properly after using

audio at least once:

(just after boot):

# echo mem > /sys/power/state

[   12.578186] PM: Entering mem sleep

[   12.678802] PM: suspend of devices complete after 92.834 msecs

[   12.688201] PM: late suspend of devices complete after 3.173 msecs

[   17.607971] Successfully put all powerdomains to target state

# aplay /dev/zero

^C

# echo mem > /sys/power/state

[  104.404663] PM: suspend of devices complete after 78.794 msecs

[  104.413909] PM: late suspend of devices complete after 3.021 msecs

[  106.601196] Powerdomain (per_pwrdm) didn't enter target state 1

[  106.607421] Powerdomain (core_pwrdm) didn't enter target state 1

[  106.613739] Could not enter target state in pm_suspend

I'm seeing this on 3.2, unable to verify on current Linus HEAD as

something else is preventing core/per low power states there.

Any ideas what could be causing this? Perhaps some clock is left enabled?
