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?= native # CFLAGS+= -O3 -pipe -march=native # for Kernel COPTFLAGS+= -O3 -pipe -march=native # CXXFLAGS+= -stdlib=libc++ CXXFLAGS+= -std=c++11 # WITH_CLANG_EXTRAS= YES WITH_CLANG_FULL= YES WITH_LLVM= YES WITH_LLVM_EXTRAS= YES # WITH_LIBCPLUSPLUS= YES # WITH_BIND_LARGE_FILE= YES WITH_BIND_SIGCHASE= YES WITH_BIND_LIBS= YES # WITH_IDEA= YES # #WITH_ICONV= YES WITH_BSD_GREP= YES WITH_BSDCONFIG= YES WITH_BSD_SORT= YES WITH_BSD_PATCH= YES # #WITH_OFED= YES WITH_NAND= YES WITH_NMTREE= YES #WITH_BMAKE= YES #WITH_CTF= YES # MALLOC_PRODUCTION= YES # PORTS_MODULES= emulators/virtualbox-ose-kmod #PORTS_MODULES+= x11/nvidia-driver I have a custom kernel, will try also the GENERIC and report in later.
