I have installed Kubuntu(v19.10) and since the first day, I'm facing this really annoying bug which freezes up my laptop(ASUS FX505DT).

The issue

I face this bug whenever I boot my laptop on battery. The laptop freezes whenever I try to use Plasma(e.g. opening the context menu). Additionally the boot time on battery(approx. 20s) is way more than on AC power(approx. 5s). Weirdly, booting my laptop first on AC power, and then remove the power doesn't cause any issues.

Please help me in debugging this issue as it is highly hindering my work.

It turned out to be an issue with the kernel being old, for the relatively new AMD Ryzen 3550H processor in my laptop. I'm currently using linux v5.6-rc5 without any issues to date.
