Definitely saw 2:1 counting on a sup720 with 12.2(33)SRA(5 or 6?) train when a L2 trunk was connected some smaller 3xxx switch.  The gig interface on the 7600 was doubling the real amount of traffic, while the 3xxx reported the accurate traffic levels.  This was observed on practically any trunk in the code mentioned.
