Hello
I have an active-active DRBD cluster using OCFS2 as the filesystem on
the drbd devices.
I started getting a "general protection fault error" when trying to
mount any one of the ocfs2 volumes I have, even when running mount on a
single node, with no mounted FSs on the other node.
The kernel trace follows at the bottom of this message. Does anyone know
what could have been happening here? The kernel version is below.

Thanks in advance,
Andre
