Severity: normal

When attaching an iPod to the firewire port on the 2.6.7 kernel, you have to manually load modules in this order:

modprobe ieee1394 && modprobe ohci1394

The sbp2 module then gets loaded automatically and the ipod is attached:

Aug 19 13:58:19 aks kernel: ieee1394: Initialized config rom entry `ip1394'
Aug 19 14:00:56 aks kernel: ohci1394: fw-host0: OHCI-1394 1.1 (PCI): IRQ=[11] MMIO=[e8002800-e8002fff] Max Packet=[2048]

That's how it should work. If you have hotplug running and plug in the iPod, the modules load in the wrong order:

Aug 16 16:07:27 aks kernel: ieee1394: Initialized config rom entry `ip1394'
Aug 16 16:07:27 aks kernel: SCSI subsystem initialized
Aug 16 16:07:27 aks kernel: sbp2: $Rev: 1219 $ Ben Collins <[email protected]>
Aug 16 16:07:27 aks kernel: ohci1394: $Rev: 1223 $ Ben Collins <[email protected]>
Aug 16 16:07:27 aks kernel: ohci1394: fw-host0: OHCI-1394 1.0 (PCI): IRQ=[11] MMIO=[f8fff$
Aug 16 16:07:27 aks kernel: ieee1394: Host added: ID:BUS[0-00:1023] GUID[374fc0002c79c410]
Aug 16 16:07:27 aks kernel: ip1394: $Rev: 1224 $ Ben Collins <[email protected]>
Aug 16 16:07:27 aks kernel: ip1394: eth1: IEEE-1394 IPv4 over 1394 Ethernet (fw-host0)

The sbp2 module loads before ohci1394, the glue between SCSI and firewire is not created, and the iPod fails to attach.

Cheers,
David
