Looks like the USB triggered a bug ("BUG: using smp_processor_id() in
preemptible"); not caused by the graphics driver.

I think Chris already wrote a patch to fix this anyway:
   https://patchwork.freedesktop.org/patch/90483/

Same USB BUG().

"*ERROR* Hangcheck timer elapsed... render ring idle"

There are a handful of bugzillas about similar issues on various
platforms; https://bugs.freedesktop.org/show_bug.cgi?id=75394 is
reported against SNB.

USB BUG() again.

All of the DMESG-WARN's above are the

"Potential atomic update failure on pipe A."

USB BUG() again.

Not sure what caused these machines to fail reboot, but my patches are
SKL-only so I don't think they're the cause.  Maybe the BUG() that was
causing DMESG-WARN's on IVB hits these platforms as well, but completely
killed them?
