I don't understand how this can be the case. The PCMCIA card plugs into a PCI card, and the PCI card only has one interrupt line. Therefore if the PCI interrupt is routed to IRQ 11, the only interrupt available to the PCMCIA card is IRQ 11. Now, the Ricoh chip has several interrupt modes, including ISA mode (for when it is connecting directly to the interrupt lines on an ISA bus), and PCI mode. My guess is that it's in the wrong mode, and therefore wiggling the wrong line. But I don't understand the "wi0: tx buffer allocation failed" message. Could this be caused by no transmit interrupt, or is there some other problem? Regards, Brian.
