firewire and/or sbp2 problem with rc2-mm3, but not rc2-mm2

[Norbert Preining]

Hi Andrew! Hi 1394 developers!

I have a bit of a problem with firewire. WIth 2.6.12-rc2-mm3 it does not
recognize my external hard disk any more:

I use an external hard disk via firewire, and when I plug it in I get:
vmunix: sbp2: $Rev: 1219 $ Ben Collins <bcollins@xxxxxxxxxx>
vmunix: Device not ready. Make sure there is a disc in the drive.

With -mm2 it was working, also with older kernels.

Now, there is also a problem with removing modules:

I remove sbp2, works.

Then I try to remove ohci1394 and it stucks:
