NetBSD cromarty 1.4X NetBSD 1.4X (CROMARTY) #9: Wed May  3 23:49:51 BST 2000     bjh21@cromarty:/usr/src/sys/arch/macppc/compile/CROMARTY macppc

I have a kue device (a Netgear EA101) attached to an ohci (Belkin add-in
card of some sort) on my macppc box (a Umax Apus 2000).  Salient dmesg
fragments follow:

Occasionally, kue0 locks up such that it stops receiving packets.  When I
was using it as my primary Ethernet interface, it would do this every few
minutes under heavy NFS load (e.g. compiling over NFS).  I'm now using it
to connect to my cable modem, and it dies once or twice a day.

Running "ifconfig kue0 down; ifconfig kue0 up" gets it running again.

I also had occasional kernel panics when it was failing frequently, but I
don't have any details to hand.

	On this machine, use kue0 for a few days.
