Re: drivers/ieee1394/sbp2.c:734: error: `host' undeclared (firstuse in this function) 2.6.3-bk3

Ok. I rebuilt the kernel 3 times. I built it twice with the following
change in sbp2.c:727
#ifdef CONFIG_IEEE1394_SBP2_PHYS_DMA
/* Handle data movement if physical dma is not
* enabled/supportedon host controller */
hpsb_register_addrspace(&sbp2_highlevel,
hi->host, &sbp2_physdma_ops,
0x0ULL, 0xfffffffcULL);
#endif

(twice to confirm that the kernel builds without throwing any errors).
It builds sbp2. I then removed the patch and built with my build script
set as:
# CONFIG_IEEE1394_SBP2_PHYS_DMA is not set

----------------------------------------------
both build all of the 1394 modules. Unfortunately, neither change gives
me devices in /proc/scsi/scsi (or /proc/partitions) with 2.6,3-bk3.
/var/log/messages doesn't show much about what is going on, but dmesg
shows:

Both of the changes allow the kernel to build, but neither gives me
devices. 2.6.3-bk2 gives me:

Thanks for your replies.
Please email me off the list if you need more information or need me to
do any testing. Also, my PCI hardware is:
00:0d.0 FireWire (IEEE 1394): VIA Technologies, Inc. IEEE 1394 Host
Controller (rev 43)
(and the controller in the devices are Oxford Semi FW900's.)

Thanks,
Bob
