Hi Al,
I have been using the firmware, version 1.1.0-rh-0.14-linaro-5 built at 08:49:30 on Feb 12 2015. With acpi=force the boot hangs. Do I need to upgrade the firmware?

The default on Fedora is notACPI; useacpi=force and it should work. You will also need to make sure you have the latest version of the Mustang firmware.
You can find kernel source here:

This is the kernel I use on my Fedora-based Mustang.
