Cool, at least card services is passing the correct base numbers to ibmtr_probe. It also means that card services thinks it can allocate the memory at D8000 and DA000 without any trouble at all. At least your stuff is dying at the very beginning and not half way through configuration.

Yep, ibmtr calculates the location of mmiobase from the seg/intr.

Hmmm, something is not talking right and I don't think it is the driver.  If the memory area is dodgy and/or used by somebody else Card Services should have refused to give us the memory and the driver would have died with a unable to allocate resource error.

Have you taken a short cruise around the pcmcia web site and seen if there are inherent problems with the 760's.
