[Ocfs2-users] SuSe Hangs when /etc/init.d/o2cb online

I would suggest to upgrade kernel to more recent version or to compile
default clean kernel by yourself.
2.6.18.53 is pretty old already, as we have 2.6.24.xx. I use 2.6.23.13 and
have no problems. If your computer just hangs - it's kernel or hardware
problem, in any other case you would see kernel Oops page.
By the way, you have different versions of ocfs2 tools and kernel module.

Do a mount and you should see configfs mounted:
configfs on /sys/kernel/config type configfs (rw)
If so, the hang is puzzling. Email opensuse help list if anyone
else has encountered the same.
Joel, Any ideas?
