Fwd: Re: [REVERT][v3.16-rc7][STABLE] usb: xhci: Prefer endpoint context dequeue pointer over stopped_trb

[Joseph Salisbury]

It looks like a new patch is available, so a revert may not be needed. 

I'll build a test kernel and have it tried out.

As I understand it, this crash will disappear with Mathias' new rework
for finding the cycle state bit in
