It looks to me you have been playing around with the USB layer of your box, which somehow locked up the interrupt processing for too long.
Ocfs2 is killing the machine in these conditions, because it needs to be shure it wont access data a nother node is looking at. Even if a single node is living, it has to do this fencing, since another one could show up in the meantime. I suggest you do not ever use USB block devices on linux production servers. The messages below, you may want to set the kernel timestamp option, so you can see if the messages are really related. (i.e. if the fencing panic is exactly 12s after the USB problem).
