I will admit I haven't done a builtworld between the these two (the last buildworld matched with the pre-Dec 21st kernel)... I am using kld modules for my testing, so I was building modules against an old world, but I don't know of anything that has changed that would cause problems.. Anyone else seeing this? -- John-Mark Gurney Voice: +1 415 225 5579 "All that I will do, has been done, All that I have, has not."
