I begin to wonder if this might be the result of a compiler bug.
The kernel in question was compiled with gcc version 4.7.0 20111117. And
there was commit to the gcc repository today that looks suspicious:
http://gcc.gnu.org/viewcvs?view=revision&revision=181466

Will have to dig deeper, but if this turns out to be the cause of the
issue, I apologize for the noise.
