https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=219399 --- Comment #29 from Nils Beyer <nbe@renzel.net> --- Hmm, are you probably a victim of the AMD Ryzen 20°C temperature offset: https://www.reddit.com/r/Amd/comments/607xg2/why_do_the_x_ryzen_cpus_have_a_temperature_offset/ ? So your real temperatures were aroung 5X°C? BTW: how do you measure the CPU temperature under FreeBSD? Regarding my script - you are correct; it's an endless buildworld and buildkernel loop. Unfortunately, to catch the AMD Ryzen "bug", you need a TMPFS mount. You can allow a user to mount TMPFS by executing following as root once: sysctl vfs.usermount=1 source: https://www.freebsd.org/doc/handbook/usb-disks.html Here's the modified script that is able to run as user: --------------------------------------------- SNIP --------------------------------------------------- #!/bin/sh OBJDIR="/tmp/ryzen_stress_test" trap "exit 1" 1 2 3 cd /usr/src umount ${OBJDIR} mkdir ${OBJDIR} mount -t tmpfs tmpfs ${OBJDIR} || exit 1 while [ 1 ]; do echo "`date` begin" BEG="`date +%s`" make -j20 buildworld buildkernel MAKEOBJDIRPREFIX=${OBJDIR} >${OBJDIR}/${BEG}.log 2>&1 ERR="$?" echo "`date` end - errorcode ${ERR}" [ "${ERR}" != "0" ] && cp ${OBJDIR}/${BEG}.log ~/. rm ${OBJDIR}/${BEG}.log done --------------------------------------------- SNIP --------------------------------------------------- In this version the suspicious log files will be saved to your home dir. Just save everything between the "SNIP"-lines to "ryzen_stress_test.sh" in your home dir and then execute as user: /usr/bin/nohup sh ~/ryzen_stress_test.sh & This spawns the stress test in the background; to kill it, execute as user: pkill -f ryzen_stress_test then the remaining buildworld, buildkernel processes should die afterwards. As user, execute: umount /tmp/ryzen_stress_test in order to unmount and erase the TMPFS buildowlrd/buildkernel temporary folder... -- You are receiving this mail because: You are the assignee for the bug.
