I realize this will sound silly, but have you checked for half-duplex on your interfaces?
Those onboard J6350 interfaces are actually 10/100/1000, so if you don't have the speed and link-mode hardcoded, do a show interfaces extensive ge-0/0/# and check the link partner section to ensure you're running full-duplex.
