Please take the current mainline (there are a couple of nasty bugs fixed in it), configure it with CONFIG_PM_DEBUG set, boot it with "no_console_suspend", run
# echo 8 > /proc/sys/kernel/printk # echo devices > /sys/power/pm_test # echo mem > /sys/power/state
If it hangs, it should leave a stack trace before and I need that trace to see what's going on. If it doesn't hang, I'll tell you what to do next.
Thanks, Rafael
