Ubuntu 20.04.3 LTS HW Compatibility

[Miguel Gameiro]

Hello,

When performing a clean install of ubuntu 20.04.3 LTS on my laptop, I started have problems booting very often. The screen presented the text message:
   soft lockup - CPU#x stuck for 22s!

If i install ubuntu 20.04.2 LTS and proceed with every update (including the kernel update included in normal updates), I am not being presented with this problem. As of right now, this is the configuration presented in my laptop:

   $ lsb_release -rd

      Description: Ubuntu 20.04.3 LTS
      Release: 20.04

   $ apt-cache policy pkgnam

      N: Unable to locate package pkgnam

   My Laptop HW:

      Laptop Model: Lenovo ideapad S130-14IGM
      CPU: Intel Celeron N4000, 2 cores, internal GPU
      RAM: 4GB
      Storage: eMMC 64GB
      Conectivity: Wifi ac and Bluetooth 4.0
      Peripherals: USB, USB-C, HDMI, all disconnected during the boot

Best Regards!
