[Ocfs2-users] kernel bug 1.2.5: any ideas ?

[Randy Ramsdell]

When running a script to test the ocfs2 volume, I am getting the kernel
bug below when it tries to delete the files.
The script itself seg faults. I can delete the files from another node,
but it hangs and never returns the terminal.

Dist:  opensuse 10.1
Kernel : 2.6.16.27-0.9-smp
