This one turned out to be caused by:

commit 3db11feffc1ad2ab9dea27789e6b5b3032827adc
Author: Jean Pihet <jean.pihet at>

    ARM: OMAP: convert I2C driver to PM QoS for MPU latency constraints

Reverting this commit causes the problem to go away, but since the OMAP PM 
constraint code was removed as well, it's unlikely that a simple revert is 
the right thing to do.

Jean could you please investigate and fix this?
