The Framework 16" laptop doesn't have a PS/2 keyboard. At bootup the
following messages are emitted:
i8042: PNP: No PS/2 controller found.
i8042: PNP: Probing ports directly.
i8042: Can't read CTR while initializing i8042
i8042: probe of i8042 failed with error -5
The last two messages are ERR and WARN respectively. These messages
might be useful for one boot while diagnosing a problem for someone
but as there is no PS/2 controller in PNP or on the machine they're
needlessly noisy to emit every boot.
Downgrade the CTR message to debug and change the error code for the
failure so that the base device code doesn't emit a warning.
If someone has problems with i8042 and they need this information,
they can turn on dynamic debugging to get these messages.
