I may have been using syslinux syntax with GRUB....Booting with pci=assign-busses modprobe=yenta_socket.bios_override=1,scsi_mod.inq_timeout=20 yields earlier and slightly different detection/config of the CardBus, error -62 during bootup as well as later error -110 like before, but otherwise little difference dmesg: [ 5.020060] usb 1-1: new full speed USB device using ohci_hcd and address 3 [ 5.200042] usb 1-1: device descriptor read/64, error -62 [ 5.484041] usb 1-1: device descriptor read/64, error -62 [ 5.764041] usb 1-1: new full speed USB device using ohci_hcd and address 4 [ 5.944040] usb 1-1: device descriptor read/64, error -62 [ 72.789531] yenta_socket: Unknown symbol pccard_nonstatic_ops [ 72.794825] yenta_socket: Unknown symbol pccard_nonstatic_ops [ 107.547840] udevd version 124 started [ 108.523839] pci_hotplug: PCI Hot Plug PCI Core version: 0.5 [ 108.676186] Linux agpgart interface v0.103 [ 108.679461] shpchp: Standard Hot Plug PCI Controller Driver version: 0.4 [ 108.994281] piix4_smbus 0000:00:14.0: SMBus Host Controller at 0x8400, revision 0 [ 109.450400] input: Power Button (FF) as /devices/LNXSYSTM:00/LNXPWRBN:00/input/input2 [ 109.464079] ACPI: Power Button (FF) [PWRF] [ 109.464303] input: Power Button (CM) as /devices/LNXSYSTM:00/device:00/PNP0C0C:00/input/input3 [ 109.480045] ACPI: Power Button (CM) [PWRB] [ 109.480264] input: Sleep Button (CM) as /devices/LNXSYSTM:00/device:00/PNP0C0E:00/input/input4 [ 109.496053] ACPI: Sleep Button (CM) [SLPB] [ 109.496286] input: Lid Switch as /devices/LNXSYSTM:00/device:00/PNP0C0D:00/input/input5 [ 109.496810] ACPI: Lid Switch [LID] [ 109.612967] ACPI: WMI: Mapper loaded [ 109.984305] Yenta: CardBus bridge found at 0000:02:09.0 [103c:3091] [ 109.984386] Yenta: Enabling burst memory read transactions [ 109.984439] Yenta: Using CSCINT to route CSC interrupts to PCI [ 109.984485] Yenta: Routing CardBus interrupts to PCI [ 109.984539] Yenta TI: socket 0000:02:09.0, mfunc 0x01a01b22, devctl 0x66 [ 110.216940] Yenta: ISA IRQ mask 0x0ef8, PCI irq 17 [ 110.216993] Socket status: 30000820 [ 110.217040] pcmcia: parent PCI bridge I/O window: 0xa000 - 0xafff [ 110.217086] cs: IO port probe 0xa000-0xafff: clean.
