Ontem à noite, meu notebook (Lenovo Thinkpad t460p) não conseguiu inicializar minha instalação do Manjaro Linux.
Um dia antes de tudo estar funcionando bem e eu não estava fazendo nada crítico (por exemplo: atualizações, instalação de novos softwares, etc). Depois de inicializar o notebook, digitar a frase secreta de criptografia (já que meu disco rígido está criptografado) e esperar que o Manjaro com o KDE inicialize, nada além de uma simples saída de texto ocorreu. O texto dizia:
mei_wdt mei::05b79a6f-4628-4d7f-899d-a91514cb32ab:02: Could not reg notif event ret=-22'
O único pensamento que eu poderia fazer era mudar para o console (com alt+F2 ), fazer login e executar startx que inicializou o KDE como de costume. Como o problema ainda existe, executei dmesg -l err (em um emulador de terminal dentro do KDE iniciado) e a seguinte saída apareceu:
$ dmesg -l err
