:
: Please help ....
:
: I have a 3COM 3c589 pcmcia network adapter.
: The adapter is operational.
:
: On both 4.1.1-STABLE and 4.2-BETA the
: adapter is initialized and output from both
: "ifconfig" and "netstat" appears okay.
:
: But I cannot ping any host on my network.
: The error message I get on 4.2-BETA is:
: ===>> ping: sendto: host is down
: On 4.1.1-STABLE "ping" will not return for
: a long time. The host MAC address appears in
: the route table though. The time is huge when
: "ping" returns finally after 3-5 mins.
:
: Any ideas on what might be the cause??

Qing-
This sounds like a classic irq conflict problem. There is probably
a device using irq 3 on the laptop that freebsd is unaware of. Based
on your dmesg output, I would suspect that you have a winmodem
pci0: <unknown card> (vendor=0x123f, dev=0x8888) at 13.0 irq 11
eisa0: <EISA bus> on motherboard
eisa0: unknown card @@@0000 (0x00000000) at slot 1
that is using irq 3.
The way to fix this is to either:
1) put the pcic in polling mode and use irq 10 for 3Com Nic
- change pcic entry in your kernel to just
device pcic0 at isa?
- add an /etc/pccard.conf with one line to force using irq 10 for
your pccard
irq 10
OR
2) try using irq 9 for the 3Com nic
- add an /etc/pccard.conf with one line to force using irq 9 for
your pccard
irq 9
OR
3) disable the onboard serial card in the bios and use irq 4 for the
3com card
- add an /etc/pccard.conf with one line to force using irq 4 for
your pccard
irq 4
Actually I would recommend using a combination or 1 and 2 such that
you put the pcic in polling mode and use both 9 and 10 for your pccards
... this would be useful if you ever want to have more than one pccard
in at a time (say an adaptec scsi card or a modem, etc).
HTH,
