Once again, the output of dmesg and the PCIC kernel configuration info would help a lot. Without it I'm only guessing. Are you running stable? 4.4-release? The pccard code was heavily revamped for 4.4 to use interrupt sharing. If you use the default setup, the interrupts for your pccards will share the PCIC controller interrupt. The irq line in pccard.conf will simply be ignored. A quick check of this is "vmstat -i". If you are using shared PCI interrupts, you will see neither the xe nor the PCIC listed. Instead you will see a "mux" device at the IRQ of the PCIC. That is the combination of the PCIC interrupts and those of the cards plugged into it. If I've guessed wrong, please include dmesg showing the boot through device probes and the PCIC kernel config line(s). R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
