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@debian.org>
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:

There are no 1394 changes in 2.6.12-rc2-mm3.

It's not very obvious who called wait_for_completion() here. Possibly
driver_unregister(), but it's way up the stack. You might get a better
trace if you enable CONFIG_FRAME_POINTER.
Still. I assume this is some interaction between 1394 and Pat's new device
management work.
