[Ocfs2-users] kernel BUG at <bad filename>:58347!

i'm looking to move forward on this, so sorry if I seem a little anxious,
I'm excited to get it going correctly.

Are there patches that I can get somewhere to apply?  Or a path I can
explore to begin getting this kernel up to speed with the correct ocfs2-dlm?
Or possibly are the correct ocfs2-dlm files in the kernel source tree for
later kernels that I could upgrade to?

Thanks for the replies so far!
