I also receive the "... check cb_mem_base" message from i82365 during bootup. However, if I remove the pcmcia_core module and then run "pcmcia start" I have the modules pcmcia_core, i82653, and ds loaded; I also have cardmgr running in the background.
Which leads me to the next point: cardmgr waits forever on its select() call, never detecting activity. cardctl shows nothing in the slots. This is irrespective of the actual card in the slot - RealPort or otherwise.
I have a Toshiba Tecra8000, and probe tells me that I have a ToPIC95-B in it. I am running a 2.2.9-17 kernel from Red Hat, and pcmcia-cs-3.1.11. The BIOS setting is CardBus/16bit. I also have Win-NT4 on the computer, which lets me use a RealPort card quite happily.
If anyone could help, it would be appreciated!
