S50n w/ 10ge Input CRCs/Discards

We're trying to deploy 10ge upstream to our S50n stack (read, all the port 0
modules are stacking modules).  We're seeing a decent amount of Input
CRCs/Discards and can't get the link to go > ~120Mbps.  We've replaced
*everything* in this link (other than the upstream RSP) -- fiber, 10ge module,
XFPs and are still seeing this problem.  Flow control is off on both ends; CPU
seems fairly low (<12%).

Any ideas on what might be going on here?  Anyone else having problems w/ 10GE
on S50?

-Doug
