Hey John,
  We've noticed that when using usb ethernet adapters on HiKey, we
occasionally see errors like:

dwc2 f72c0000.usb: dwc2_hc_chhltd_intr_dma: Channel 0 - ChHltd set,
but reason is unknown
dwc2 f72c0000.usb: hcint 0x00000002, intsts 0x06200029

dwc2 f72c0000.usb: dwc2_hc_chhltd_intr_dma: Channel 11 - ChHltd set,
but reason is unknown
dwc2 f72c0000.usb: hcint 0x00000002, intsts 0x04200029

Sometimes followed up by a usb error in the driver, something like:
asix 1-1.2:1.0 eth0: asix_rx_fixup() Bad Header Length 0x36000807, offset 68

Curious if you've seen any reports like this?

We haven't seen it with a older 4.4 tree we've been using (which had a
bit more out of tree changes to it), but it was discovered with the
4.9 branch we have, and I've confirmed its happening with the upstream
kernel too, so I need to try to jump back to some older trees to see
where it might have first cropped up.

thanks
