NE64 Link problem in 10BT

my application is a serial to ethernet bridge. I use a MC9S12NE64 with openTCP stack. I set the internal PHY in 10BT, and on some switches( very few), I do have the following problem: the link goes up and down very fast and I am not able to send any packets. This problem occurs only in 10BT, not in 100BT or in autonegociation mode. One of the failing router is Linksys SD208.
Has anybody ever heard of this problem ?
Thanks for your help.

Best regards,
