I'm thinking of a way to debug this too. The symptom may hint at a
use-after-free. Could you enable KASAN in your tests? (On the flip

Seems like DH87RL was working with 3.2.0-55-generic-pae unfortunately
we don't have such a board for testing and customer patience is
limited to bisect the kernel.
Does anyone have a clue what modification could have killed USB 3.0
support within those releases?
It does not seem to be SG support.
I just got another USB 3.0 bugreport, the entire system crashed. That
particular customer already filed a bugreport in November 2013 that
his system is in a bad state when using some USB 2.0 media devices
which even have opensource drivers built into the kernel.
USB 3.0 support with Linux seems to
