I'm having some odd problems with what appears to be a 3C905-TX ethernet
interface (PCI ID 9050) as supplied built in to the system board on a
Dell Optiplex GXi.  Plan 9 is installed as a stand-alone terminal with a
kfs on the local disk.

After entering the user name and passwd I get the error message "#l0:
sataus 0x803, diag 0x2000" (presumably this is the first time the system
touches the network hardware.)  Perusal of the code indicates that this
is an "rxUnderrun" and "shouldn't happen."  I also see this error if I
disconnect the network cable during a boot.

The hardware seems to be in order.  It certainly worked when I had NT
installed on the system in question.  I see link lights at both ends,
and the activity light on the system indicates that the hardware is
seeing traffic on the network.

If I try to ping, I see the activity light on the corresponding port on
the hub flash about once a second, as one might expect.  But the
interface doesn't appear to receive anything; the arp cache shows that
it is WAITing to resolve the address of the system that I am trying to
ping to.

I've applied all the patches except the last two (which I don't believe
contain any ethernet updates.)

Any ideas???
