Linksys PCM200

Good localtime

I've got a Linksys EhterFast PCM200 CardBus ethernet adapter recently,
and now I'm trying to make it work with FreeBSD 5.2.1-R, on a Sony PCG-748
notebook. Seems like it is based on a DEC 21143 chipset, specifically
ADMtek Centaur-C. After the changes I made to dc(4) (see diffs below),
the OS recognizes the card, and is able to attach it. I can assign an IP
to dc0, and when I connect it to a switch, the link type [100baseTX, FD]
is properly recognized. All 3 LEDs on the card ("Link/Act", "10/100",
"FD/COL") appear to work as intended. It even seems arp packets can be
sent and recieved (while in promisc mode - monitoring with 'tcpdump').
However, if I try to run dhclient, ping, etc - nothing else works:
"dc0: watchdog timeout"

Any thoughts?


`dmesg`: (booted without ACPI because otherwise the OS halts after a while)

BTW, found some driver which seems to support the card:
