next in thread | raw e-mail | index | archive | help
Have any of you successfully used the "dc" driver with a Digital
DE500-BA card on an Alpha? I am running -current from April 9
(revision 1.9 of if_dc.c). Here are the symptoms:
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
This same card with the same cable and switch works fine when I boot
Tru64 Unix (aka Digital Unix 5.0).
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. (BTW, what is "the problem" referred to in that log
message?)
Dmesg output is below. (The kernel was built May 20, but the
sources are actually from April 9.)
