I built the next test kernel, up to the following commit: c0f3f90cf454dd845dcc443afa4f0e312a8eaee0
The test kernel can be downloaded from: http://kernel.ubuntu.com/~jsalisbury/lp1547619 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.
