Len, the patches in https://bugzilla.kernel.org/show_bug.cgi?id=16040
don't appear to have made it into 2.6.34.1, even though they were
written a month earlier.  This 2.6.34 regression is preventing at least
one tester from testing 2.6.34.x kernels for a different regression.

Did we forget to backport those fixes into -stable?

Thanks.
