I'm pretty sure that there is no reliable fix for this on 4.6.2. The problem was not (hopefully) finally fixed until about a month ago. If you upgrade to 4.7-Release or -Stable, it SHOULD be better. Alternatively you might well get by with updating the drivers from cvs. Be sure to get those from the stable branch, RELENG_4. Get all of the files there that have been updated in 2 months or less and odds are pretty good. But this is always a bit risky as some dependencies may have changed between 4.6.2 and now. It's probably easier to go to 4.7. R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
