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):
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.
which kernel is this ? (version , smp/non smp etc etc)
I am using kernel 2.4.9-10smp but it also fails on 2.4.9-7 and on both smp and
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.
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.
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.
Is some one working on this issue .We need to make it work for our oracle
database on Rac
