The code for warm reboot is overly specialized, and makes it hard to add other key cominations for testing. BUG=chrome-os-partner:13763 BRANCH=link TEST=manual 1. boot system 2. hold down (in order) R+T+alt+VolUp. System does not reboot. 3. let go of T (so only R+alt+volup are pressed). System reboots.
