We are bisecting between those two kernel versions to identify the commit that introduced this regression. Some of the test kernels I post will be bad and some will be good. At the end of the testing the bisect will point to one particular commit.
I built the first test kernel, up to the following commit: aee3bfa3307cd0da2126bdc0ea359dabea5ee8f7 The test kernel can be downloaded from: http://kernel.ubuntu.com/~jsalisbury/lp1657994 Can you test that kernel and report back if it has the bug or not? I will build the next test kernel based on your test results.
