Boot lento no Fedora

Olá,

Sou bem novo no uso de Linux devido ao tipo de software que preciso (basicamente CAD) mas quando isso não é necessário, uso o Linux. Comecei com Ubuntu, usei o Linux Mint por algum tempo, mas o Fedora eu achei mais interessante por, pelo menos no ano passado, quando migrei, ser um dos poucos com Gnome atualizado. Uso Fedora e Windows 11 em dual boot. Possuo duas partições EFI porque uma, se não me engano, já veio de fábrica para recuperação do sistema.

Ocorre que no Mint o boot era extremamente rápido, até mais rápido que o boot no Windows, mas ao migrar para o Fedora isso não ocorreu. Até olhei alguns passo-a-passo de como reduzir o tempo de boot, mas eles sempre focam em serviços que não estão ativos no meu notebook ou que estão, mas consomem pouquíssimo tempo. Vou tentar colar alguma coisa pra ver se ajuda. Lógico que ter uma solução pronta seria ótimo, mas um norte pra saber o que tenho que procurar já pode me ajudar.

Tenho 8GB de ram e 12GB de SWAP, porém não há opção de "hibernar" em nenhuma parte do menu, apenas "suspender". Em alguns momentos parece que ele suspende, apagando a tela e ficando com a luz indicadora de power piscando, e retorna normalmente quando pressiono alguma tecla. Em outros momentos, ele não suspende e mantém a luz do power acesa, mas não retorna com tecla nenhuma, precisando ser reiniciado.

Essa dica é apenas referente ao problema de hibernar, correto? Comentei porque pode ter a ver, mas o principal problema é o tempo de boot. De qualquer forma, fiz isso e estou aguardando pra ver se dá algum erro ao retornar. Não é sempre que ele trava, então é preciso testar algumas vezes. Obrigado!

-semana passada tive que desativar Zram pq boot demorava quase 2 minutos (Ci5 + 8 RAM + 120 SSD)
-agora demora menos de 30 segundos

Aqui demora cerca de 32 segundos, mas com Windows 11 ou Linux Mint era bem mais rápido, acredito que perto de 15 segundos. Nada grandiosa minha configuração: SSD 256, i7 8ª geração, 8GB de ram. Inclusive lembro que no Mint havia alguma opção no grub que fazia o boot demorar bem menos. Algo como "quiet splash" pra adicionar ou remover, mas não me recordo. Lembro que até fiz logo que instalei o Fedora, mas não resolveu.

Cara,te recomendo urgentemente mexer no "/etc/initramfs-tools/initramfs.conf" e alterar a compressao para xz e deixar o nivel dela como 9.... fora isso da uma olhada em softwares e modulos que estão subindo junto com o sys (aqueles que são "inuteis" para você)

Rapaz, tem alguma configuração relacionada a isso no Fedora? Aqui eu não encontrei esse caminho... tentei procurar por initramfs.conf pra ver se era em outro local, mas ele não encontrou.

Ahh provavelmente o "initramtools" n deve estar instalado ent ^^ mas vou ver aqui,porque faz 2 versoes q nem vejo o fedora, e eu tava vendo o seu systemctl-analyze e o unbound ta subindo ai e levando mais de 200ms pra levantar (se você nao tem ou não precisa de um servidor dnv,melhor desabilitar no boot pelo menos)
Pode fazer isso logado cok o root ou com o sudo: systemctl disable unbound #para desabilitar o unbound iniciar junto ao boot

Será que era isso mesmo?

[peter@fedora ~]$ sudo systemctl disable unbound

Failed to disable unit: Unit file unbound.service does not exist. 

Imagino que o vilão tá entre o initrd e o userspace

[peter@fedora ~]$ systemd-analyze

Startup finished in 3.513s (firmware) + 7.496s (loader) + 1.279s (kernel) + 11.923s (initrd) + 13.148s (userspace) = 37.361s 

graphical.target reached after 13.128s in userspace. 

Mas entre achar que está ali e conseguir saber o que buscar, tem um mar sem nenhuma ponte. Encontrei um fórum do Fedora que parecia falar da mesma coisa
https://discussion.fedoraproject.org/t/slow-boot-initrd-dracut-initqueue-service/77354/5

E nessa discussão, alguém levantou que tinha que fazer algo descrito aqui:
https://bugzilla.redhat.com/show_bug.cgi?id=1976653

Mas é algo de 2021... e em 2022 tinha gente comentando que não funcionou. Já tô pensando que é isso mesmo e que vai ser sempre lento mesmo, infelizmente.

De qualquer forma, obrigado pela força. E sobre a zram do primeiro comentário, de fato parece ter resolvido o problema de travar ao hibernar. Ainda trava às vezes, mas é menos frequente que antes. Agradecido também por essa ajuda!
