I have a Psion Gold Card Netglobal 56K+10/100Mb CardBus card, now this was very stable under Linux 2.4 kernels using the epic100 driver included in the PCMCIA-cs package maintained by David Hinds, however since updating to kernel 2.6 the card will not power on.

Under 2.4, two modifications were made to enable functionality, first an edit to /etc/pcmcia/config.opts:
Code:
include port 0x1000-0x17ff
uncommenting the above statement to include high port numbers, and secondly to pass two options to the module:
Code:
debug=1 full_duplex=0,1
which I believe sets the network and modem respectively to full duplex mode and enables debug messages.

There is an unofficial port of the driver for 2.6 and that's included in the kernel, the card is recognised and the driver installs/loads via the hotplug event. But the network link/activity lights do not come on.

I can set the IP address etc via ifconfig, but the card does not function.

Here is the transcript of the system messages when the card is inserted:
