This is in drivers/pcmcia/au1000_db1x00.c: db1x00_pcmcia_hw_init(): skt->irq = AU1000_GPIO_8; /* = 40 */ Now the CF is working fine.

RE: pcmcia - failed to initialize IDE interface
I think I isolated the problem: in ide-cs.c, ide_config() is calling pcmcia_request_irq(), and this function happens to set irq=35. This irq was not rejected later in ide_probe.c, hwif_init(): ide0: Disabled unable to get IRQ 35 I noticed that the old kernel 2.4.26 used irq=40 here. So I tried to force pcmcia_request_irq() to set irq=40, like follows: --- linux-2.6.20.7-orig/drivers/pcmcia/pcmcia_resource.c 2007-04-15 21:08:02.0 +0200 +++ linux-2.6.20.7/drivers/pcmcia/pcmcia_resource.c 2007-04-27 09:20:41.0 +0200 @@ -867,6 +867,7 @@ printk(KERN_WARNING "pcmcia: request for exclusive IRQ could not be fulfilled.\n"); printk(KERN_WARNING "pcmcia: the driver needs updating to supported shared IRQ lines.\n"); } + irq = 40; c->irq.Attributes = req->Attributes; s->irq.AssignedIRQ = req->AssignedIRQ = irq; s->irq.Config++; and this happens to work: ide_config() succeeds, and finally I can mount the CF and use it. Other values for irq (i tried 39, 41) won't work either. Which would be the correct way to make pcmcia_request_irq() use the correct value of 40?

pcmcia - failed to initialize IDE interface
