I changed to -j20 to see if that would recreate the problems that Ulrich is seeing, but buildworld runs fine for me, in about 2 hours. I've never seen the non-current pmap warning on the system that uses a usb ssd drive as root, but I've seen it with nfs root. BTW, the DIAGNOSTIC option adds a LOT of performance overhead to an arm system without adding a lot of value. I usually leave it off, sometimes turn it on when I encounter a problem to see if it generates more info (usually it doesn't). -- Ian
