Description Larry Byars 2001-10-23 14:26:07 UTC

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:
Always

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.

I'm also having the similar problem.

Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem
persists.

The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, 
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
