Hi, Sorry for high latency on that. The Motorola suggestion patch looks good. Have not been able to reproduce the lost remote wakeup event with that patch in the kernel. However, I'm experiencing a suspend/resume issue somewhere in usbnet/cdc-ether/cdc-wdm/cdc-acm which are limiting any long term stability tests. Oliver knows more. It seems that having additional debug enabled affects the timing, I'm having a hard time triggering the XactErr problem I've been seeing for a while.
