[Ocfs2-users] kernel: Kernel BUG at aops:249

[Sunil Mushran]

Please file a bug in oss.oracle.com/bugzilla with the full strack trace.

The kernel BUG line looks wrong or at least incomplete. Is this the
full trace? If you have hit this on more than one occasion please do mention
that in the bugzilla. Maybe even upload the stack trace from those 
instances too.

In case you are wondering, no, I have not seen this stack trace before.
