Keep in mind that this might actually be a user space problem and that different kernel versions work or don't work only be coincident.
If you can get me an SSH access to the box I could take a look as well. Attaching a debugger to the process in question shouldn't be to hard.
By the way, if I understand correctly, if the bug is in userspace and was introduced around the same time kernel 3.17-rcX went out, would it appears when using a previous kernel version? I'm trying to figure out a way to distinguish one from the other because from where I am in the bisection, I was unable to reproduce the bug with a 3.16 kernel, but it does appear before 3.17-rc1...
