3Com Corporation 3c905B 100BaseTX [Cyclone] (rev 30) @ 10 Mbit only

[Gerald Fischer]

Hi!

I've got a 3c905B Cyclone in my box, but it will not work at 100Mbit with
linux. It does 100 Mbit with Windows :-(

maybe someone can do anything with the debuging-information:

with mod-option 4 it falls back to 10 Mbit:

with mod-option 6 it is set to 100 Mbit, but it does not work. :-(

if you need any further information (vortex-diag, ...) please inform me.

I hope someone can help me,
