From Bugzilla Helper:
User-Agent: Mozilla/4.77 [en] (X11; U; Linux 2.4.4 i686)

Description of problem:
The IEEE1394 driver module, sbp2, used for accessing disks, tapes, etc.
through a Firewire connection hangs the system when loaded requiring a
manual power cycle to recover. 

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

How reproducible:

Steps to Reproduce:
1.boot the system, log in as root.
2. modprobe ohci1394
3. modprobe sbp2	

Actual Results:  The system "hangs" - becomes totally non-responsive either
from the keyboard or from the network.

Expected Results:  The module should have loaded. Note that no devices are
attached to the Firewire controller.

Comment 1 Arjan van de Ven 2001-10-23 14:28:06 UTC
which kernel is this ? (version , smp/non smp etc etc)

Comment 2 Larry Byars 2001-10-23 15:04:06 UTC
I am using kernel 2.4.9-10smp but it also fails on 2.4.9-7 and on both smp and 
up kernels.

Comment 3 Larry Byars 2001-10-23 16:54:57 UTC
Oops...sorry, got a bit confused with the digits. However, it fails with the 
2.4.7-10 (default kernel with enigma install, both smp and up versions) and 
also with the updated 2.4.9-7smp and up kernels from up2date.

Comment 4 Larry Byars 2001-10-25 19:09:21 UTC
Some additional information. This problem only seems to occur with SMP kernel. I
have a Dell Precision 530 Workstation with 2 1.7MHz Pentium IV Xeon processors
and 2 Gb memory. I'm now communicating with the linux1394 group at SourceForge
to see if I can find anything else. I have tried their latest CVS sources but
with the same result.

Comment 5 Need Real Name 2002-05-02 21:53:26 UTC
I also see the same problem.  If I boot with 2.4.9-31smp the machines freezes
when I modprobe sbp2.  If I boot just 2.4.9-31 then it works fine.

Thanks for the bug report. However, Red Hat no longer maintains this version of
