Wow, this turns out to be much worse than I thought...I've tracked down the problem to the commit of the new physical memory allocator at Sat Jun 16 04:57:05 2007 UTC. Before that, no kern/122380; after that, kern/122380 applies. Any ideas where to go from here? Thanks, Geoff On Mon, Apr 21, 2008 at 12:29:38PM -0600, M.
