The Intel i3-3220 crashes with blinking characters on the screen (I use the built-in GPU for console displaying). A C2D 8400 - same setup, crashes also very early while booting. The whole system/world is built with CLANG, this is the setting of the /etc/src.conf: CPUTYPE?=3D native # CFLAGS+=3D -O3 -pipe -march=3Dnative # for Kernel COPTFLAGS+=3D -O3 -pipe -march=3Dnative # CXXFLAGS+=3D -stdlib=3Dlibc++ CXXFLAGS+=3D -std=3Dc++11 # WITH_CLANG_EXTRAS=3D YES WITH_CLANG_FULL=3D YES WITH_LLVM=3D YES WITH_LLVM_EXTRAS=3D YES # WITH_LIBCPLUSPLUS=3D YES # WITH_BIND_LARGE_FILE=3D YES WITH_BIND_SIGCHASE=3D YES WITH_BIND_LIBS=3D YES # WITH_IDEA=3D YES # #WITH_ICONV=3D YES WITH_BSD_GREP=3D YES WITH_BSDCONFIG=3D YES WITH_BSD_SORT=3D YES WITH_BSD_PATCH=3D YES # #WITH_OFED=3D YES WITH_NAND=3D YES WITH_NMTREE=3D YES #WITH_BMAKE=3D YES #WITH_CTF=3D YES # MALLOC_PRODUCTION=3D YES # PORTS_MODULES=3D emulators/virtualbox-ose-kmod #PORTS_MODULES+=3D x11/nvidia-driver I have a custom kernel, will try also the GENERIC and report in later.
