I noticed that (33ad261 usb: dwc2: host: spinlock urb_enqueue) is now in linuxnext, so I pulled it (and many other) changes into the chromeos-3.14 kernel for testing. I still see the problem that Heiko reported. Note that aside from the warning, this causes all sorts of "spinlock recursion" issues and an eventual freeze on my system. Until Yousaf's patch has landed it seems as if we should do a revert of (33ad261 usb: dwc2: host: spinlock urb_enqueue) to avoid regressing existing systems. -Doug -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in
