Ahhh, the inscrutable corrupted packet nightmare journey. Good luck in your quest... you shall need it. Here are some tokens to hopefully guide you past the yawning canyons with bugs and dragons ready to snatch your sanity and rob you of rest... Simply ask: what are the essential characteristics of this loss? That is the first search, for truth. 1. power up randomly messes up some configuration - like reset Steve mentioned or just corrupted config register 2. cold vs. hot power up: different effects? Ie: results are different? 3. your imagination... is "few" really important? It's not clear the losses really correlate to anything systematic. Could be normal, from your description. 4. Chip bug. You didn't mention if the loss is at remote rcvr or on your board. Try dumping registers when no loss, then after losses. Stop traffic immediately upon loss detection. Verify loss is really on the link and not on the comparison path (ie: where packets are compared).
