I am running -current from April 9 (revision 1.9 of if_dc.c). This same card with the same cable and switch works fine when I boot Tru64 Unix (aka Digital Unix 5.0). Here are the symptoms when I use FreeBSD's "dc" driver: With ifconfig media set to autoselect: - boot system: lights on the switch say it's 100 Mbit half-duplex. (The switch is an Allied Telesyn (CentreCom) FS716.) - ifconfig says it's full-duplex - unplug cable from switch and replug it: switch lights now say full-duplex - send a big file via ftp: system prints TX underrun warning, switch lights go off and come back up half-duplex. - unplug cable from switch and replug it: switch lights now say full-duplex - send a big file again: everything is OK now With ifconfig media set to 100baseTX full-duplex: - boot system: lights on the switch say it's 100 Mbit half-duplex - ifconfig says it's full-duplex - replugging cable doesn't change anything With ifconfig media set to 10baseTX/UTP: - works fine, but hey, it's only 10 Mbit I tried backing up to revision 1.8 of if_dc.c to remove this commit: msmith 2000/03/10 21:20:58 PST Modified files: sys/pci if_dc.c if_dcreg.h Log: Teach the 'dc' driver how to pick up settings left over by the SRM on alpha systems. This is an expedient if not entirely elegant solution to the problem. It didn't help. Dmesg output is below. (The kernel was built May 20, but the sources are actually from April 9.)
