next in thread | raw e-mail | index | archive | help
I'm asking for help getting a JMicron JMC250 network interface working
under FreeBSD. It appears that the jme driver is not functioning
correctly on this hardware. The machine is an Asus Eee Box B202 with a
JMicron JMC250 ethernet chip on the motherboard. I'm running the
8.0-RELEASE Generic kernel. The machine boots fine, recognizing the
interface as jme0, but I can't connect to any hosts on the network. When
I ping the router or another host on the subnet, I see the packet lights
flash on the router, but I get no ping responses. The arp cache remains
empty.
I know that it's not a hardware problem, because the machine can connect
to the network fine under Windows XP, using the same NIC, cable and
router port. Under FreeBSD I can assign an IP address, take the
interface down and up, and can see the link light on the router turn off
and on again when the interface comes up, but I can't ping any hosts.
When I ping the EeeBox from another host the EeeBox MAC address is added
to the other hosts' arp cache, but no ping response packets are
received. On the EeeBox the arp cache remains empty. Perhaps the EeeBox
can transmit packets, but somehow not receive?
I have tried booting with MSI and MSI-X disabled (in loader.conf:
hw.jme.msi_disable="1", hw.jme.msix_disable="1"). The interface came up
without MSI, but I was still unable to connect to any hosts. I tried
disabling the following interface options using ifconfig, also without
result: -rxcsum, -txcsum, -tso, -wol, -vlanhwtag.
