Interestingly I removed the int3403_thermal module, and disabled thermald's critical shutdown using thermal.nocrt = 1. However, it still shutdown with critical temp reached thermal zone 4 (80c). Anything left I can try, cause I lost a lot of work during the last shutdown and they only get more frequenent.

It's getting really bad. To the point where Ubuntu is barely usable.

For me it's even more worse, my cpu would be idleing at 30-40C and suddenly it will shutdown with thermal thermal_zone3: critical temperature reached (80 C), shutting down Could it be a sensor problem? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to thermald in Ubuntu. https://bugs.launchpad.net/bugs/1873083 Title: Lenovo Yoga C940 frequently does thermal shutdown Status in linux package in Ubuntu: Incomplete Status in thermald package in Ubuntu: Confirmed Bug description: On a bit higher load and especially if Laptop is charging, very often Kernel does an emergency thermal shutdown. thermal thermal_zone3: critical temperature reached (80 C), shutting down It says 80 C, but sensors command shows that temperatures hovering close to 100C before the shutdown happens. dmesg is often also full of these (for each core): mce: CPU2: Core temperature above threshold, cpu clock throttled (total events = 246766) When I boot to Windows, it seems that CPU is throttled more aggressively on load and thermal shutdown doesn't happen with a similar load, but CPU frequencies drop to 1600 range, while in Ubuntu they are 2800 range. I would rather have more throttling that computer shutting down randomly without the ability to save work. Is there a workaround?
