Linux 2.4.21 (+SuSE patches)
My new laptop uses an ENE CB1410 cardbus bridge.
I found that my pcmcia ISDN card (AVM A1 PCMCIA) does not work correctly because yenta does not seem to recognize any ISA interrupts for me and consequently the hisax driver refuses to load.
Mar 9 20:29:38 linux kernel: Yenta IRQ list 0000, PCI irq5 Mar 9 20:29:38 linux kernel: Socket status: 30000006
The driver in Win XP in this case assigned IRQ 3. By adding a faked ISA irq mask to yenta.c i was able to get the card working.
Could this be a problem that the ENE CB1410 needs some fixup during initialization to recognize the ISA IRQs or should i simply change the irq_mask in yenta.c?
I found a datasheet of the ENE CB1410 on the Internet: http://ftp.cizgi.com.tr/turknote/CT10/CT10%20Service%20Manual/EnE%20Cardbus%20Controller%20Datasheet.pdf
Would anybody with some more depth in this area feel inclined to look into this? I'm happy to test any changes.
