           Summary: SBP2 driver doesn't appear to register a block device?
    Kernel Version: 2.5.65
            Status: NEW
          Severity: normal
             Owner: [e-mail]
         Submitter: [e-mail]

Distribution: Red Hat 8.0
Hardware Environment: Single Processor Pentium III, details below
Software Environment: 
Problem Description: Loading ieee1394 SBP2 driver doesn't result in a usable
block device appearing.

Steps to reproduce: 
Attach firewire drive. 
Boot 2.5.65, load ieee1394, ohci1394, sbp2 modules.

The firewire to IDE bridge is correctly detected, as is the actual hard drive
attached to the bridge.  Everything seems to be fine, but the drive does not
show up in /proc/partitions, and I can't mount /dev/sda1.

(Under a 2.4.x kernel, /dev/sda and /dev/sda1 would show up at this point)

Here is more information: ieee1394 and SCSI settings from .config:

CONFIG_SCSI=m
CONFIG_BLK_DEV_SD=m
CONFIG_BLK_DEV_SR=m
CONFIG_CHR_DEV_SG=m

CONFIG_IEEE1394=m
CONFIG_IEEE1394_OHCI1394=m
CONFIG_IEEE1394_SBP2=m

dmesg after loading the modules has:
