Description of problem:

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.Install null with OnStream FW-30 connected
2.Complete first boot
3.Up2date kernel

Actual Results:  sbp2.o gets included in initrd, but ieee1394 and ohci1394 are
not there, so the insmod sbp2.o fails (lots of missing symbols reported on the

Expected Results:  sbp2.o should not be there, so there is no insmod failure.

Additional info:

Since the OnStream FW-30 is a tape drive, not a disk that could contain a file
system that matters during boot, there is no reason for kudzu to cause sbp2 to
show up in an initrd.

Here is what my initrd looks like:

[root@fallguy tmp]$ zcat /boot/initrd-2.4.18-12.2.img >/tmp/initrd
[root@fallguy tmp]# mount -o loop -t ext2 /tmp/initrd /mnt/floppy
[root@fallguy tmp]# ls /mnt/floppy
bin  dev  etc  lib  linuxrc  loopfs  proc  sbin  sysroot
[root@fallguy tmp]# ls /mnt/floppy/lib
ext3.o  jbd.o  sbp2.o  scsi_mod.o  sd_mod.o
[root@fallguy tmp]#

Concretely, this is caused by kudzu's creation of the following line in

alias scsi_hostadapter sbp2

This is how a FW-30 shows up:

[wriede@fallguy wriede]$ cat /proc/scsi/scsi

Can you post your /proc/bus/ieee1394/devices file?

Comment 2 Bill Nottingham 2002-08-30 19:21:17 EDT
initrd stuff fixed in 3.4.25-1.

firewire and usb-storage aren't put in the initrd in current mkinitrd packages.
