[vortex-bug] Re: 3c59x 0.99H and 3c905B (Cyclone) problems

[Bob Ramstad]

Bill Owens suggested that it might be an auto-negotiation problem and
requested output from "vortex-diag -mm".  In the interest of
generating as much meaningful data as possible, i ran it:

* with the machine working perfectly hooked to a 10 mbps hub
* with the machine recabled to the 10/100 mbps hub (not working)
* after a reboot with it still cabled to 10/100 mbps hub (not working)
* with the machine working fine recabled to the 10 mbps hub

Bill Owens also suggested trying the 3Com driver 3c90x.  I've actually
tried it and also had no luck.  (I don't really care what driver I
use, as long as it works, but I assumed that the 3c59x would have
better support as it is used by more people and is open source, so I
came here for assistance first.)  If someone wants to walk me through
some troubleshooting with the 3c90x driver, I'd be happy for the help
on that front as well.
