Linux and the DLink DMF 560TX Modem/LAN Combo PCMCIA Card

This PCMCIA has worked with older Linux distributions. Its modem has worked perfectly well out of the box under various Linux distributions and kernels 2.2, 2.4, 2.6. Its ethernet network card used to work nicely out of the box, but it does not work under newer 2.6 kernels, like 2.6.13-15.18 of SuSE Linux 10.0. In Ubuntu 8.04.1 the modem did not work either. But here is a solution. The main hint is from Bugzilla. The error message is like:

pcnet_cs: unable to read hardware net address for io base 0x8300.

In newer versions of Linux the modem of the card does not work either. A remedy (at least under Ubuntu 8.04.1): Add to /etc/pcmcia/config.opts a line

exclude port 0x8000-0xbfff

where the address range is the I/O window taken from a boot log. In my case there was a message

pcmcia: parent PCI bridge I/O window: 0x8000 - 0xbfff

in /var/log/dmesg. Then 0x300 is chosen instead 0x8300 and the card works.
