You're correct, the Oops only happened with your original set of patches. After adding the latest patches it no longer occurs. However I still get other errors, with vanilla 3.19rc7, your patched 3.19rc5 kernel and my 3.19rc7 with all your patches applied. All of the log reports look similar to me. I'll submit a separate report for this issue.
