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 -john
