If not, it probably indicates GMAC is in weird state which in turn indicates initialization was not complete for the controller. > Ifconfig shows the link correctly (100 or 1000 Mbit, > depending on where I plug the cable in). > I also swapped cables just to be sure, but it made no > difference. > If you cold-boot the box with UTP cable plugged in to re1 does it make any difference? > I'm running a recent stable/9 (about 14 days old). > What's the best way to debug this problem? At the I would check whether GMAC is active when driver detects a valid link. Add a code like the following to re_miibus_statchg() to get the status of RL_COMMAND register. You would get the status whenever a link is established with link partner.
