I'm happy to merge this and give it some time in -mm, before it goes to mainline, but if no-one is testing on those older opterons/turions etc then we're not going to know we regressed until its too late. If it hasn't been tested yet, any chance you can scrounge some up at AMD and give it a spin just to be sure? Thanks, Dave --=20 http://www.codemonkey.org.uk
