Loaded 5.3RC2 from the iso onto my new 4GB dual Opteron server today. After getting cvsuop installed, I got 5.3-RELEASE and did a buildworld. It never completed: repeating it several times resulted in random crashes in various places throughout the build. A bit of googling suggested adding a line to /boot/loader.conf hw.physmem=2G This permitted the buildworld to complete so I built a new kernel using the following config file: include GENERIC options SMP options VM_KMEM_SIZE_MAX=(400*1024*1024) Leaving the 2G line in loader.conf, I managed to complete the entire build/install process normally. SMP seems to work properly as well. I removed the 2G limit from loader.conf and tried several more buildworlds and the random crashes returned. A bit of googling suggested adding the following to /etc/make.conf: CFLAGS= -O -pipe -g -DKVA_PAGES=512 COPTFLAGS= -O -pipe -DKVA_PAGES=512 This had no effect, the random crashes continue during buildworlds. I tried raising the limit to 3G and the crashes returned. Any suggestions as to how to proceed would be greatly appreciated. /\/\ \/\/
