Hello, Following my previous email, I have finally reached to make the watchdog work by updating the bios. I updated the bios to the 0062 version (https://www.intel.fr/content/www/fr/fr/download/19698/709584/bios-update-tntgl357.html).

I have some problem to make the watchdog work. The iTCO_wdt driver is well initializing and creating a watchdog device in dev directory: iTCO_wdt iTCO_wdt: Found a Intel PCH TCO device (Version=6, TCOBASE=0x0400) iTCO_wdt iTCO_wdt: initialized. heartbeat=30 sec (nowayout=0) When forcing the watchdog open (cat >> /dev/watchdog), the timeleft value isn't decreasing and a reboot never happened. No reboot also when forcing a kernel panic. I have also tried a Fedora 35 distribution as well as a Ubuntu 20.04, with the same result. Has anyone encountered this issue before? Is the Intel NUC11TNBi5 watchdog supported by the iTCO_wdt driver? Thanks, Kévin L'hôpital Free Software Consultant | Rennes, Fr Savoir-faire Linux Jami: klhopital
