I can access the io space through a module, the card generates interrupts but I'm not able to get the interrupt handler working. This is because the QSpan and the Winbond doesn't pass interrupts. I guess that some registers are incorrect (EPPCbug?). Could someone tell me in which place of the kernel the settings should be done. The kernel is 2.2.13 with some patches. some logs: #cat /proc/interrupts CPU0 5: 3231 8xx SIU cpm 15: 0 8xx SIU tbint BAD: 0 # cat /proc/pci cat uses obsolete /proc/pci interface PCI devices found: Bus 0, device 3, function 0: ISA bridge: Winbond W83C553 (rev 5).
