Use a different cable to the same switch port, first.  If you change 
both the cable and the switch port, you won't know if the problem was 
the cable or the switch port.

If the problem persists with a different cable, *then* try a different 
switch port.

Yeah, the low link speed is no surprise given the long negotiation time.

Google-fu also turns up a suggestion that the switch doesn't negotiate 
properly in some cases, and that the problem can be resolved by 
disabling power saving mode on the switch, in its management interface.
