Hi,
my new laptop (IBM Thinkpad G40) has an integrated NIC made by broadcom.
It's a BCM5901 card for which support was added in the tg3 driver a few
weeks ago (both in 2.4 and 2.6-test). However, the device doesn't work,
it insmods just fine and claims the hardware, but the machine never
responds to ping messages and the led indicating network activity is
never activated.
Broadcom has released a driver of their own (bcm5700) which works with
kernel 2.4.21. When I try that combination it works fine, however, the
bcm5700 driver wont work at all on recent 2.4 or 2.6 kernels.
Does anyone know what is wrong with the tg3 driver? Has anyone tried
using it on a 5901 card with success?
Regards,
David

Trying unplugging/plugging the cable, or ifdown+ifup cycle, and let me
know if that fixes things.

Hi,
I tried unplugging/plugging the cable a few times along with ifup and
ifdown a few times in different variations. It didnt seem to do much,
one interesting thing that I noticed was that the Windows XP host that
this laptop was connected to with a crossover cable during the testing
reported the link as being down when the NIC was ifup'ed and vice versa.
After being bored with ifup/down and cable pulling I tried some
modprobe/rmmod as well. This proptly hosed the system, the "ifconfig
eth0 down" command is frozen, unkillable and consumes 100% CPU right
now. ifconfig on another console to check if the card "is still there"
also froze. Well, at least the network led woke up, its on constantly
right now :-)
Ideas?
//David
PS
With the tg3 driver the card is reported as a 33Mhz PCI card, with the
bcm5700 it's reported as a 66Mhz PCI card, could this make a
difference?

Yes, and it also works just fine when I use it at work on a daily basis
with the 2.4.21 kernel (+ broadcoms own bcm5700 driver) or Windows XP
(also with broadcoms own driver).
