Tenho um laptop Eluktronics MECH-17 G2 cujo teclado integrado (a opção mecânica Cherry MX) é completamente não funcional com qualquer distribuição Linux que experimentei. Essa lista inclui Ubuntu (18.04 e 24.04), Debian, Mint, Arch, Nobara, Fedora e OpenSUSE Tumbleweed (que é o que tenho instalado atualmente). Todas essas distribuições são consistentes, pois o teclado funciona perfeitamente no GRUB (e Windows/BIOS), mas fica completamente morto quando inicializado. O touchpad funciona perfeitamente, assim como os teclados USB. Se eu adicionar o noapicparâmetro do kernel, o teclado funciona, mas meu touchpad para de funcionar, e o sistema só consegue ver/usar 1 dos meus 16 núcleos de CPU, então essa obviamente não é uma solução de longo prazo.
Eu verifiquei /proc/interruptse parece que o i8042 está consistentemente sendo registrado no índice 1 e colocado na CPU12, e notei que se eu pressionar botões no meu teclado e verificar /proc/interruptsnovamente, o número de interrupções aumenta. Então, pelo menos alguma coisa está acontecendo. Se eu inicializar com noapic, tudo é manipulado pela CPU0 e os outros 15 núcleos da CPU não aparecem na saída.
Os outros parâmetros do kernel que tentei e que não ajudaram são:
- i8042.dumbkbd=1
- i8042.nopnp
- i8042.nomux
- i8042.redefinir
- i8042.direto
- nolapic - congela imediatamente após o GRUB
- acpi=ht - também faz com que monitores externos não funcionem
- pci=noacpi - congela em uma tela preta durante a inicialização
- acpi=off - o teclado funciona, mas muitas teclas são perdidas e todo o sistema fica muito lento
- irqpoll e irqfixup - tentei ambos separadamente e juntos, mas meu sistema congela durante a inicialização de qualquer maneira
Aqui está a saída de dmesg | grep -iE "acpi|apic|keyboard|i8042|serio" com os parâmetros acpi.debug_layer=0xFFFFFFFF& acpi.debug_level=0xFativos:

A propósito, o fabricante oficialmente não oferece suporte ao Linux, então não estou recebendo nenhuma ajuda deles.
Muito obrigado a todos que reservaram um tempo para responder. Tenham um bom dia.
