Per Andy's last comment: "It seems the issue may be to do with the Panda's hub / ethernet chip idle / wakeup characteristics but since there are no hub registers in there settable from Panda side AFAIK (there are some settable in the missing EEPROM that can configure the hub / Ethernet bridge)"
Is there anyone that is willing to handle? Or provide additional insight?
Actually I don't know where to go with debugging it any further. There was some talk it might be to do with Transaction Translators and to meddle with kernel config around those, however there are no non-Highspeed devices connected and it still acts the same.
I guess we could try to contact the hub / ethernet bridge chip vendor for comment.
