sbp2 firewire failure on kernels 2.6.1-1.61, 2.6.2-1.81

[Michel Alexandre Salim]

I get the following errors when I turn on my external hard drive
enclosure:
------------------------------------------------------------------
ieee1394: got invalid ack 11 from node 65472 (tcode 4)
ieee1394: got invalid ack 11 from node 65472 (tcode 4)

------------------------------------------------------------------
sbp2 does *not* get loaded automatically.

If I unload ohci1394 and reload it, I get:

Still no drive detected, until I attempt to mount a partition:

What is the status of firewire support on FC2-devel? It is quite worrying
it seems to be retrogressing ever since 2.4.21 was released (first
requiring rescan-scsi-bus.sh, and now this). Is there any possibility of
shipping a 2.4 kernel in addition to 2.6 for FC2 final?

Hardware's Sony Vaio Z1MP, Centrino (Pentium-M 1.3GHz) with a USB memory
stick interface.

Has anyone run into a similar problem? Bugzilla has nothing to say on
that - I'll probably file a report tomorrow.

Thanks,
