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
