Unless you're seeing link related problems (link doesn't come up and those are scrolling continuously) you shouldn't worry about those messages. MTP2 is designed to work around link layer hickups such as this. You may see better performance though if you set your dchan to hardhdlc instead (though that only works on the TE4xxp and TE2xxp).
