Eu tenho a máquina virtual VMware executando o Debian Wheezy. Eu compilei meu próprio kernel 3.14. Eu notei dmesg é inundado com mensagens pci BAR 7: can't assign io (size 0x1000) .

Eu não tenho ideia do que essas mensagens significam. A VM parece estar funcionando OK, não vejo nenhum problema. No entanto, estou incomodado com essas mensagens de erro e ficaria feliz se pudesse me livrar delas.

Alguém poderia me explicar

1) o que essas mensagens significam

2) como posso me livrar deles

ATUALIZAÇÃO

na verdade, o dmesg contém mais de 550 linhas de logs (debug) relacionados ao PCI. Eu colei a parte relevante aqui

Como posso me livrar desses registros?

Eles não são úteis e estão apenas inundando meus registros

Parece-me que você está enfrentando um erro relacionado à alocação de memória para a taxa de transferência de dados do barramento PCI, apesar do fato de estar executando em uma VM. Embora eu não esteja familiarizado com o VMWare, suspeito que possa haver uma configuração relacionada à emulação de PCI ou à alocação de memória que você possa ajustar para corrigi-lo.

O tópico do fórum mencionado no final deste post sugere que um problema semelhante pode ser resolvido com a desativação da ACPI, embora eu não possa garantir a precisão do referido tópico.

Eu suspeito (embora eu não tenha nenhuma informação para respaldar isso, portanto, tome isso com um grão de sal) que pode ter algo a ver com a arquitetura que você está emulando. Se você estiver emulando x86 de 32 bits, sugiro tentar emular a versão de 64 bits do mesmo software e testar se ele também ocorre lá.

Quanto à remoção do log, acredito que isso pode ser feito facilmente usando dmesg -C , ou talvez (se você quiser automatizá-lo) configurar uma tarefa Cron para executar a tarefa mencionada a cada hora.

Está relacionado à alocação de memória para o throughput de dados do barramento PCI. Ative a opção Traffic Shaping no vSwitch através do vSphere Client.

Eu tentei isso e funciona bem para mim.
