Just a followup to my own mail... I switched the DC21040 driver to use I/O mapped access and now everything works (I forgot I modified the UnixWare driver to be I/O mapped so that it could support the DEC DE425 EISA Ethernet Card). So I've bounced this off the DC21050 PPB folks. Who knows? I just might be the first person to try memory mapped access over the DC21050 on Triton. Just another verification that living on the bleeding edge of technology can be bloody...
