On my trusty -current/amd64 laptop, I built memtestplus-5.01nb1, copied /usr/pkg/mdec/memtestplus to /, and added menu=Boot memtest:boot memtestplus to /boot.cfg.
memtestplus starts on boot, I am given the option for safe mode, but come what may, as soon as testing starts, the laptop reboots. Does memtestplus work for you? Cheers, Patrick
