<pre>Could you try the following branch:
<a href="https://github.com/ideak/linux/commits/suspend-fix">https://github.com/ideak/linux/commits/suspend-fix</a>
Also could you get a serial console log when the hang happens (preferably from
an RS232 port, or if that's not available via a USB->serial adapter)? See
Documentation/serial-console.txt to set things up.
Also make sure you have enabled the following kconfig options:
CONFIG_LOCKUP_DETECTOR=y
CONFIG_HARDLOCKUP_DETECTOR=y
CONFIG_DETECT_HUNG_TASK=y
and pass the 'debug', 'no_console_suspend' kernel parameters.</pre>
