RHEL + mensagens do kernel + como identificar se as mensagens do kernel são indicadas em um problema

  • 772

temos o servidor RHEL 7.2 antigo e notamos mensagens de kernel muito estranhas

não tenho certeza se a linha abaixo definiu um problema

[ffffea00a5a00000-ffffea00a5bfffff] PMD -> [ffff880015000000-ffff8800151fffff] on node 0

mas também compartilho a mensagem completa e espero obter mais detalhes sobre eles

    Essas mensagens são informações de depuração impressas durante a configuração da tabela de páginas ; eles mostram informações sobre o “diretório do meio da página”, que é uma das estruturas de dados usadas pela MMU x86 para mapear endereços virtuais para endereços físicos.

    Essas mensagens não indicam um problema.
