Sorry, not had time to bisect it.
Tested with gcc 4.1.2 and gcc 4.3.2
Use this config if yours does not exhibit the problem:
http://uml.devloop.org.uk/kernels/kernel64-2.6.31.config

Cheers

Please try this patch:

http://patchwork.kernel.org/patch/48759/

It should fix your problem.

What I can do here is to suggest -stable team to include this patch in the
next update for .31. Greg?
