Hello, I crash this night (between 3hours uptime and 6hours uptime, i was sleeping) with 6.6.16 and without voltage correction. (red led flashing) (I crash with version "TRANSITION_DELAY 5000" that i copy/paste upper) Do you know which kernel was running when your box crashed? -> 6.6.28 but maybe with your TRANSITION_DELAY 0 version because i copy/paste from forum and then until now i use github version copy/paste upper I install 6.6.28 without voltage correction and look result List of packages i installed: base-files_24.5.0-trunk-12.4+deb12u5-bookworm_arm64__1-bookworm-1armbian1-Ba4f9-U12.4--deb12u5-R55fa.deb armbian-config_24.5.0-trunk_all__1-SA8477-B0293-R448a.deb linux-dtb-current-rockchip64_24.5.0-trunk_arm64__6.6.28-Sba15-D440d-P9dc2-Ca832H66b1-HK01ba-Vc222-Bf15a-R448a.deb armbian-plymouth-theme_24.5.0-trunk_all__1-Bfcdb-R448a.deb linux-image-current-rockchip64_24.5.0-trunk_arm64__6.6.28-Sba15-D440d-P9dc2-Ca832H66b1-HK01ba-Vc222-Bf15a-R448a.deb armbian-zsh_24.5.0-trunk_all__1-SAbfee-Baafd-R448a.deb linux-u-boot-helios64-current_24.5.0-trunk_arm64__2022.07-Se092-Pe990-H8c72-V65aa-Bf5f6-R448a.deb root@helios64:~/tmp# uname -a Linux helios64 6.6.28-current-rockchip64 #3 SMP PREEMPT Wed Apr 17 09:19:38 UTC 2024 aarch64 GNU/Linux root@helios64:~/tmp# for i in $(seq 1 100); do ./cpufreq-switching-2-b ; done If not crash, i try TRANSITION_DELAY 0 version if not crash TRANSITION_DELAY 0 version, i stay with this setting If crash i try voltage correction Keep in touch

you mean you have no crash running cpufreq-switching-2-b five times with 6.6.16 and 6.6.28? Yes not crash today. I post soon full test pattern and result with 6.6.16 and then 6.6.28 with source of cpufreq-switching-2-b from https://gist.github.com/prahal/8fab73325eb0d7091ad7c4627bf8e25a compil with gcc -o cpufreq-switching-2-b cpufreq-switching-2.c So it crashed with which kernel? Did you rebuild cpufreq-switching-2-b between the test that crashed and the ones that did not? Yes i rebuild because i build in /tmp directory that what a ramdisk... and lost binary with crash Now i store binary on emmc 😉 I do next test with my armbian 24.2.1 build my self with official framework without any another tune then i do exact same with packages kernel armbian 24.5 build my self with official framework upgrade on my 24.2.1

Hi, Fisrt, i restore my backup with 6.6.16 and run cpufreq-switching-2-b 5 times and cpufreq-switching-b 2 times root@helios64:~# uname -a Linux helios64 6.6.16-current-rockchip64 #1 SMP PREEMPT Fri Feb 23 08:25:28 UTC 2024 aarch64 GNU/Linux root@helios64:~# cat /etc/default/cpufrequtils ENABLE=true MIN_SPEED=408000 MAX_SPEED=1800000 GOVERNOR=schedutil root@helios64:~/tmp# ./cpufreq-switching-2-b ; ./cpufreq-switching-2-b ; ./cpufreq-switching-2-b ; ./cpufreq-switching-2-b ; ./cpufreq-switching-2-b root@helios64:~/tmp# ./cpufreq-switching-b ; ./cpufreq-switching-b No crash with your program Second, I installed build my self this over my 24.2.1 build with 6.6.28: linux-dtb-current-rockchip64_24.5.0-trunk_arm64__6.6.28-Sba15-D440d-P9dc2-Ca832H66b1-HK01ba-Vc222-Bf15a-R448a.deb linux-image-current-rockchip64_24.5.0-trunk_arm64__6.6.28-Sba15-D440d-P9dc2-Ca832H66b1-HK01ba-Vc222-Bf15a-R448a.deb reboot and do: root@helios64:~/tmp# uname -a Linux helios64 6.6.28-current-rockchip64 #3 SMP PREEMPT Wed Apr 17 09:19:38 UTC 2024 aarch64 GNU/Linux root@helios64:~/tmp# ./cpufreq-switching-2-b ; ./cpufreq-switching-2-b ; ./cpufreq-switching-2-b ; ./cpufreq-switching-2-b ; ./cpufreq-switching-2-b ; ./cpufreq-switching.b ; ./cpufreq-switching.b Not crash… freq seem change in htop program monitor but load isn’t at 100% on cpu… load seem idle… it’s normal, same with 6.6.16 or 6.6.28? if it’s normal: not crash with your cpufreq-switching-2-b & cpufreq-switching.b program on my helios crash with my pattern test on 6.6.16 and not with 6.6.27 and 6.6.28 What do you think about my results ?

hi, i build 2 version from your site: root@helios64:~/tmp# ls cpufreq-switching-2-b cpufreq-switching-2.c cpufreq-switching.b cpufreq-switching.c I run this version cpufreq-switching-2-b ? and after running your program, i think automatic freq change don't change but stay a last freq fixe, i all right?

Hi, Not change millivolt value because i afraid to do a mistake I just setting differentes values of freq For moment i am at 400-1200Mhz and not lose connection... Can you explain me command to change milivolt setting if i have futur courage or crazy spirit to try this idea? And i have question, i install my 6.6.27 Kernel .deb build my self with official framework, then i reboot and do my pattern 3 times without crash... Today i reboot and lose connection approximately 10min after boot when i set upper than 1400mhz... milivolt value work before reboot why not after, setting not change? Now i do: git clone --depth=1 --branch=main https://github.com/armbian/build ; cd build/ ./compile.sh kernel BOARD=helios64 BRANCH=current dpkg -i *.deb to install Kernel 6.6.28 4 packages reboot and... uptime 18min... not loose connection ! i become crazy !

....Grrrr I reboot... and now i lose network connection random time (approximately 6-10min) after full boot... and i lose access by USB wire to console... return in unstable world... I become CRAZY ! Back to 400-1200Mhz max schedutil, if lose connection... back to 1200 1200 Performance (equal to fix freq 1200)
