Hi,
I am using a DM3730 with Android patched Linux kernel 2.6.32 from the gumdroid project (https://github.com/gumdroid) and when I try to suspend my device I get the following error:
# echo 8 > /proc/sys/kernel/printk
# echo 15 > /sys/module/wakelock/parameters/debug_mask
# echo mem > /sys/power/state
request_suspend_state: sleep (3->3) at 38078856731 (2000-01-01 00:00:45.220061560 UTC)

I have added a few extra printk's and turned on the debugging in the kernel. I have modified the Android /init.rc so that all it does is boot to a busybox shell and load nothing else. I am booting from an SD card and therefore enabled CONFIG_MMC_UNSAFE_RESUME in the kernel as well as CONFIG_OMAP_RESET_CLOCKS. My PM layer selection is OMAP_PM_SRF. I have tried booting from NAND and I get the same result.
Any assistance with this is greatly appreciated.
Ben
