I'm kind of new to the whole Cluster/OpenAIS/GFS2-tools thing, so bear with me...

Specifically, which package is causing the problem?  Cluster?  I assume when you mean upstream code, I assume you mean the code that is part of the kernel, as, yes, I am running a pretty new kernel...  

While I would like to wait until the problem is fixed, is there a known good version of one package (Kernel, Cluster, OpenAIS, GFS-tools, etc.) or combo that would get me up and running?  I need to have GFS2 running a week ago, and due to various problems, I am already horribly late in getting this deployed.
