The EHCI Probe (usb_hcd_pci_probe) fails with "controller already in use" error because the request_mem_region gives an error. I think the Problem is that the CardBus bridge eat the mem. As a refence you can compare the CadrBus mem window on 2.6.28.1 with 2.6.16.11. At the moment I have no idea how can I fix this resource conflict ... I found a pcibios_fixup_bus fuction that reorganize the dev->resource[i] values but I'm not sure if this is called during pci init. I'll check this now. Is there a PCI guru for mips on the list? Kind regards, Frank Kernel 2.6.28.1 output pci 0000:00:0c.0: PME# supported from D1 D3hot D3cold pci 0000:00:0c.0: PME# disabled pci 0000:00:0c.1: PME# supported from D1 D3hot D3cold pci 0000:00:0c.1: PME# disabled pci 0000:00:0c.2: PME# supported from D0 D1 D2 D3hot D3cold pci 0000:00:0c.2: PME# disabled pci 0000:00:0d.0: PME# supported from D0 D1 D2 D3hot D3cold pci 0000:00:0d.0: PME# disabled pci 0000:00:0d.1: PME# supported from D0 D1 D2 D3hot D3cold pci 0000:00:0d.1: PME# disabled pci 0000:00:0c.0: BAR 0: can't allocate mem resource [0x50000000-0x4fffffff] pci 0000:00:0c.1: BAR 0: can't allocate mem resource [0x50000000-0x4fffffff] pci 0000:00:0d.0: BAR 0: can't allocate mem resource [0x50000000-0x4fffffff] pci 0000:00:0d.1: BAR 0: can't allocate mem resource [0x50000000-0x4fffffff] pci 0000:00:0c.2: BAR 0: can't allocate mem resource [0x50000000-0x4fffffff] pci 0000:00:0d.0: CardBus bridge, secondary bus 0000:01 pci 0000:00:0d.0: IO window: 0x001000-0x0010ff pci 0000:00:0d.0: IO window: 0x001400-0x0014ff pci 0000:00:0d.0: PREFETCH window: 0x40000000-0x43ffffff pci 0000:00:0d.0: MEM window: 0x44000000-0x47ffffff pci 0000:00:0d.1: CardBus bridge, secondary bus 0000:05 pci 0000:00:0d.1: IO window: 0x001800-0x0018ff pci 0000:00:0d.1: IO window: 0x001c00-0x001cff pci 0000:00:0d.1: PREFETCH window: 0x48000000-0x4bffffff pci 0000:00:0d.1: MEM window: 0x4c000000-0x4fffffff PCI: Enabling device 0000:00:0d.0 (0000 -> 0003) PCI: Enabling device 0000:00:0d.1 (0000 -> 0003) Kernel 2.6.16.11 output PCI: Bus 1, cardbus bridge: 0000:00:0d.0 IO window: 00001000-000010ff IO window: 00001400-000014ff PREFETCH window: 40000000-41ffffff MEM window: 42000000-43ffffff PCI: Bus 5, cardbus bridge: 0000:00:0d.1 IO window: 00001800-000018ff IO window: 00001c00-00001cff PREFETCH window: 44000000-45ffffff MEM window: 46000000-47ffffff PCI: Enabling device 0000:00:0d.0 (0000 -> 0003) PCI: Setting latency timer of device 0000:00:0d.0 to 64 PCI: Enabling device 0000:00:0d.1 (0000 -> 0003) PCI: Setting latency timer of device 0000:00:0d.1 to 64
