Hmmm, this is strange. I've also upgrade to the 2.2.18 ibmtr driver and
pcmcia 3.1.21 as I had the same problem with VMware as Friedemann
reported it. And I also had these "Transmitter busy" messages from time
to time. But since the upgrade, I've *never* had them at all!

These messages used to occur more likely when I connected my machine
from a PCMCIA card in the internal slot on one day and from a card in
the docking station's slot on the other day (although these are
identical cards). I still do this occasionally, but as said I haven't
had any more problems so far ...

A little bit baffled,
Markus
