 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 :-)

 I'm still not sure it is software or hardware problem.

I didn't tried 12 kernel on this hardware.

 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...
