Public bug reported:
While testing the 24.04.3 ubuntu-server-arm64+raspi images, I had a hard
time doing the vcgencmd test:
```
Check the CPU clock speed using vcgencmd
Stress the CPU by doing yes > /dev/null &
Run sudo vcgencmd measure_clock arm after about 5 sec
Kill the stress process
The output should be around 1.4GHz
```
With 100% CPU usage, the keyboard would fail to register inputs (or
register ghost inputs) quite frequently - I spent 10 minutes just
entering the vcgencmd as it would skip over inputs, and then repeat a
particular input a lot of times (including backspaces)
This was tested on a Raspberry Pi 3B+. It can be an issue with my
keyboard as well, but this only shows up when the CPU is stressed.
