Public bug reported:
After updating from kernel 6.14.0-32 to 6.14.0-33, multiple hardware
components stopped working on my laptop:
Touchpad is not detected and not working (xinput list shows no touchpad)
Wi-Fi adapter not detected (no wireless option in Settings)
Audio output missing (no sound devices listed)
Screen brightness controls no longer work
All of these devices function normally when booting into the previous
kernel 6.14.0-32.
