Hello ndst, Groovy 20.10 has reached EOL, and so has the HWE kernel in Focal 20.04 based on the 5.8 kernel. Could you please update the HWE kernel to the latest 5.11-based version (5.11.0-25.27~20.04.1) and check whether the problem persists? The easiest way is to update the hwe meta package (likely linux-generic-hwe-20.04).
