iMX28 Suspend-to-RAM

We have a custom imx28-based board running Linux 2.6.36. We are testing the suspend-to-ram function and we are getting an intermittent crash when attempting to go into the suspend-to-ram state.  The crash occurs in dpm_suspend_noirq when the device_suspend_noirq function is being called for all device entries on the device power management list. The contents of one of the entries is corrupted/modified, causing a crash in the list manipulation code.
