Kernel panic on kernel 5.4 Lenovo 100S

Hello everyone,

Wanted to report a issue when using kernel 5.4 or higher on my Lenovo 100s laptop.

After a few hours of use it would lock up and the capslock key would be flashing and repeat any audio was playing signalling some sort of kernel panic.

To help do I look at my journalctl for a log?

Can you post the hardware info?

Sure thing, currently using 4.19 because it’s stable

I have a similar CPU model: Intel Celeron N3150.
Only with kernel 4.19, the computer runs fine.

The GUI freezes with kernel 5.7.

Yeah seems to be a issue when using newer kernels on these cpus

Anyone got any feedback on what the issue is and if this will be fixed on newer kernels?
