Installed 32-2.4.20-pa20 as the -21 only had the Config, no vmlinux or 
System.map there.

Well, at any rate, it doesn't complain about tulip0/eth0 anymore ... but 
it still doesn't pass any traffic or obey mii-tool. 
"10 Mbit, half duplex, autonegotiation complete, remote fault, link ok" 
... even after "mii-tool -F 100baseTx-HD eth0".

Looks better now anyway ;-/

No extras, sorry. They're in real use. (don't tell me that's a bad choice 
- well, if you know of something else to get a H to do 100BT ...)

Well, the builtin adapter isn't doing "just fine" either, but that may be 
firmware-related - when set to 100-HD with mii-tool it goes to 100-FD or 
some such that the hub (yes) doesn't like at all. I suppose I should get 
around to updating the box's firmware. 
 
Oh well, it autonegotiates to 10HD and that works. The other end is a HP 
J3294A (ProCurve 10/100 hub) that obivously can't do anything FD ... and 
yes, I did use other stuff to test the 6911 too. 



And additionally, there's some (non-network-related?) stuff in dmesg that 
I don't remember seeing before, "HP SDC: Transaction add failed: 
transaction already queued?" Is that the HIL stub or something? Should I 
pursue that too?
