Exactly. Also, this could be related to that volume going read-only.
But if so, you will atleast see the following message:

        printk(KERN_CRIT "File system is now read-only due to the 
potential "
               "of on-disk corruption. Please run fsck.ocfs2 once the file "
               "system is unmounted.\n");

If the code is the same, then it could be that the difference is in the 
build.
But what, how, I cannot say.

BTW, maybe a good idea to fsck your volumes.
