hi russel i tried to use the pcmcia-cs driver again (2.4.24-ck1 ... they didn't work with the hdsp, either (afaik, the pcmcia-cs driver never worked with the hdsp, but i'm not sure about that) the dmesg output was: PCI: Found IRQ 5 for device 02:00.0 PCI: Sharing IRQ 5 with 01:00.0 PCI: Found IRQ 11 for device 02:00.1 PCI: Sharing IRQ 11 with 00:1f.3 PCI: Sharing IRQ 11 with 00:1f.5 PCI: Sharing IRQ 11 with 00:1f.6 O2Micro OZ6933 rev 01 PCI-to-CardBus at slot 02:00, mem 0x20000000 host opts [0]: [pci/way] [pci irq 5] [lat 168/176] [bus 3/6] host opts [1]: [pci/way] [pci irq 11] [lat 168/176] [bus 7/10] ISA irqs (default) = 3,4,7,9,10 PCI status changes cs: cb_alloc(bus 7): vendor 0x10ee, device 0x3fc5 cs: cb_free(bus 7) cs: cb_alloc(bus 7): vendor 0x10ee, device 0x3fc5 PCI: No IRQ known for interrupt pin A of device . ALSA ../../alsa-kernel/pci/rme9652/hdsp.c:5031: unable to grab memory region 0x0-0x1bff RME Hammerfall-DSP: no cards found i have no idea of the differences between the cardbus drivers of the kernel and of the pcmcia-cs project ... anyway, the hdsp is working on a certain area of memory, that the pcmcia-cs driver can't grab the kernel driver can ... i disabled acpi and apic and used pci=biosirq as kernel flag maybe this can give you a hint ... anyway, i hope thomas can comment on that... cheers and thanks for your help...
