Ok. I got the message when trying to rmmod ohci1394 (both ohci1394 and
ieee1394 show up with lsmod).  I was trying to unload/reload ohci1394
as  /proc/partitions didn't show sdb or sdc devices.

To confirm the hardware is there and ok:
2.4.21-pre6 shows /proc/partitions as:
major minor  #blocks  name
 
   8     0    1048575 sda
   8    16  134217727 sdb
   8    17  134215011 sdb1
   8    32  134217727 sdc
   8    33  134215011 sdc1
   3     0   20010312 hda
   3     1      30208 hda1
   3     2    1050840 hda2
   3     3   18922680 hda3
   3    64   80043264 hdb
   3    65   80035798 hdb1
(so the hardware is there).......

The complete error message I get when I try to rmmod ohci1394 is:
[root@localhost root]# /sbin/rmmod ohci1394
Device 'fw-host0' does not have a release() function, it is broken and
must be fixed.

I built 2.6.0-test6 with gcc 3.2.2.  I am using module-init-tools-0.9.14
to load/unload kernel objects.  The base system is redhat9.0 upgraded
with yum.

The firewire controller is:
00:0d.0 FireWire (IEEE 1394): VIA Technologies, Inc. IEEE 1394 Host
Controller (rev 43) on I/O port:
ec00-ec7f : VIA Technologies, Inc. IEEE 1394 Host Controller

If more information is needed, please mail me back directly as I am not
on the list.  I will try to reply within a few hours.
Cheers,
Bob
