Hm. Is there a clock polarity setting? Either in McPDM or the twl6040? If clock polarity would be wrong, then it may depend on power supply noise if the data line is sampled correctly and the previous bit value creeps in or some random bit is read.
Some trivia: we had this exact same issue just after pandora's mass production start back in 2010... https://git.openpandora.org/cgi-bin/gitweb.cgi?p=pandora-kernel.git;a=commit...
That is funny :) Making the Pyra a real Pandora 2 (that was the original working title).
Except for that the clock polarity was configurable with a software setup on the Pandora... which doesn't seem to be the case with the Pyra :/
