I've just started fuzzing with the patch applied. Often it takes a few
hours to trigger the bug.
Added question about this bug. It appeared that the crash was triggered
by the BTS driver over-writing kernel memory. The data being written, was
this user controllable? Meaning, is this a security issue being fixed, or
just a crashing issue?
