The sun node joins, and gets counted as a vote, but in the "Quorum" line of /proc/cluster/status, there's a disagreement between the sun node and the x86 nodes.  The x86 are running, with a vote count of 3, and the sun box is "frozen" or something, with a quorum count of 0.  Attempting to leave the cluster (for any node) resulted in a failure code, and the load average on the first node skyrocketed (12 before it stopped being usable) - dlm was taking 100% CPU, and I got a kernel oops too.

I've checked in a fix. There was a change made recently and I forgot the

Ah well, but that means I would have to test GNBD on mixed-architecture ;-)
