Bug#754857: Acknowledgement (linux-image-3.2.0-4-amd64: Sporadic kernel crashes)
Please see following link:
https://bugzilla.kernel.org/show_bug.cgi?id=75521
It's a Linux USB stack kernel bug related with xhci and currently in
progress, it has nothing to do with the userspace drivers those
drivers even make it easier to debug.
