Almost fresh. It was installed from some rather fresh 13 snapshot and then upgraded to r341157 and custom kernel via source update. Now I'm trying to update it second time without luck. First upgrade was not so painful, as far as I can remember :-) > Can you please narrow the problem down to a specific kernel revision?

I didn't tried 12 kernel on this hardware. > I'm running one amd box and a number of intel boxes with various cpus, > no issues. Me too, but this is only one box which have 13 and try to compile something, all other boxes are either 11/12 or are small NanoBSD installations without toolchain... -- Best regards, Lev mailto:lev@FreeBSD.org
