Hi All, 

Recently my system prompted me for updates and I accepted them as usual, but after updates I started facing severe thermal issues and my laptop started shutting down automatically due to thermal issues.

Code:

Sep 21 08:59:07 linuxlite-Vostro-3500 kernel: [  511.326710] thermal thermal_zone0: acpitz: critical temperature reached, shutting down Sep 21 08:59:07 linuxlite-Vostro-3500 kernel: [  511.326723] reboot: HARDWARE PROTECTION shutdown (Temperature too high)

 After long debug I found that latest kernel (5.15.0-153-generic) update was the issue. I had to remove new kernel and go back to old kernel (5.15.0-133-generic) to get my system stable again. Seems they removed support for old hardware, intentionally or by mistake I don't know.

Code:

sudo apt remove linux-image-5.15.0-153-generic linux-modules-5.15.0-153-generic sudo update-grub

 I wanted to raise this issues so that it can be escalated to the relevant team and fixed in future version. Below are log details and system information. Please let me know if any more information is needed.

First thing to do is run through the normal upgrade path from 6.4 to 6.6 then allow the new kernel to install.
