Comment(by rsmith):

 No Blocker is ok.  But is not 100% fixed.

 There are 3 failure modes that still exist.  Even with the latest
 firmware.  They are now just much harder to trigger.

 1) Many superfast keypresses at startup.  What I call the "wild monkey"
 case.  The controller ignores commands in this case.  Hardware problem.
 Reported to EnE.  As of now a Won't fix.

 2) Pressing keys prior to the start up sound.  If you press keys prior to
 the startup sound then those keys are sent up to the host.  Its possible
 then to confuse OFW when it checks for a keyboard and it assumes no
 keybaord. Mitch and I have a fix for this but it only works on 1.5 or 1.0
 that would use backported EC code.  The OFW keyboard code is shared
 between Gen 1 and 1.5 so this fix needs a bit of thought before
 implementation.

 3) Gridlock after a reflash. Even with latest firmware this has happened
 during C1 at least once.  OFW sends a command to the EC but for some
 reason its never processed. This is still not understood.

 Modes 1 and 2 are soft lockups in that using the power button to power
 cycle will clear the error but mode 3 still requires a total removal of
 power.
