It is normally associated with a physical cable problem, or a bad NIC
that isn't within spec.
The 5500's use PHY's that are much more tolerant of the physical
electrical characteristics of the signal from the client. The 6500's
use PHY's that are spot on with the spec. So if you have any cabling or
NIC's that are marginal, you will see these errors.
There is a hidden command to disable the error disable "feature":
set option errport enable
(This actually turns of the "disable" feature off.)
