I recently installed 4.7-R on a machine that runs vinum and have had no trouble with my system. I also have run vinum start multiple times and all it seems to do is creade another md device (md?: malloc disk). I have not experienced the page fault or kernel crash issue you are describing. I am using a vinum mirror over two 4-GB drives.
