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

-------->8--------

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.

>How-To-Repeat:
	On this machine, use kue0 for a few days.

 Point of information: this is a well known problem on iOpeners (uhci).
 Charles Hannum has claimed that the problem is even worse when they are
 connected through external usb hubs.  aue(4) does not exhibit the problem.

 Yes, I get this problem too.  Some quick debugging revealed nothing.
 Doing an up and down of the interface seems to fix the problem for me.

 It's possible that it's a firmware problem.  There's a newer version of the
 firmware (I think the Linux driver has it) that we should test.  Unfortunately,
 I have zero time to work on USB right now.
