Makes me wonder what happened a few months ago when it seemed like the camera locked up, and removing the lens and re-setting the lens and body cleared it up...
Thanks for confirming.
The answer to your wonder is the body (or lens) had jammed early in the sequence/cycle before the lens lock was set.
Id try the lens off the body for any errant symptoms...
