An initial bisect already reported that was the first bad commit, so it can't be marked bad. The oops on memcpy() happens after commit a4a23f6 is reverted. The oops on memcpy() did not happen before a4a23f6 was committed, so I assume this new oops was introduced by a change later. Right now I'm bisecting down the oops on memcpy() by updating the bisect with good or bad, depending if the test kernel hit the oops. I then revert a4a23f6, so that revert is the HEAD of the tree each time before building the kernel again(As long as the commit spit out by bisect is after when a4a23f6 was introduced).
