I fear my Pixhawk is suffering from some sort of hardware problem :(

Initially all was well with my Tarot 650 quad after installing the Pixhawk.  Loiter was rock solid and nothing seemed out of the ordinary.  During additional testing however things have been going downhill.

Three times now I have an issue with a similar symptom.  The HUD shows the quad rolling grossly to the left when video shows it is not.  Today I had two instances.

1)  While in land mode the quad was drifting to the right.  I added left roll input to counter to no avail.  After entering almost full left roll it still was drifting.  Upon releasing the stick to center the quad rolled drastically to the right forcing me to take over in stabilize.  In Stabilize I was barely able to get the quad back to level using almost full left roll.

2)  On an auto mission the quad got 3/4 of the way to waypoint 2 before stopping.  It was directly where it was supposed to be but claimed it was tilted almost all the way to the left (even though video shows it was almost perfectly level).  It was as if it was trying as hard as it could (so much that forward progress stopped) to counter-act this imaginary force from the left.

This was the mission it was trying to run.

When it stopped this was the HUD display:

This is what the video shows at this same time:

Please help; I really need to get some work done with this craft but cannot seem to get it to work for me.  This is coming on the heels of almost losing it due to a DCM bad heading incident :(  I have 2 fixed wing planes with Pixhawk and APM with no issues...this quad is just kicking my butt!  If you need any additional info please let me know.
