Lançado o Linux 5.8 - Mas não atualize se for rodar máquina virtual.

A algumas horas atrás foi lançado o kernel 5.8 conforme monitorado neste Tweet.

5.8: mainline Version: 5.8 (mainline) Released: 2020-08-02 Source: linux-5.8.tar.xz PGP Signature: linux-5.8.tar.sign Patch: full https://t.co/92ScQXt9Ou #linux #kernel

— Linux Kernel Releases (@LinuxKReleases) August 3, 2020

Uma lista completa das novidades pode ser conferida em https://kernelnewbies.org/Linux_5.8

Porém, esta atualização vem com alguns efeitos colaterais. Primeiro com os drivers da NVIDIA. Mas isso é facilmente resolvido instalando o último driver disponível que é o 450.57. Veja se a sua distribuição já atualizou ou procure em https://www.nvidia.com.

Agora a dor de cabeça fica por conta da área de virtualização.

Acessando o blog http://rglinuxtech.com/, foi encontrado um relato que diz que o drive do VMware apresenta alguns problemas e, mesmo com alguns patches, qualquer tentativa de iniciar uma máquina virtual pode reiniciar a máquina host sem aviso, conforme o log indicado no mesmo blog mencionado.

Ainda não existe uma solução, conforme indicado em https://communities.vmware.com/thread/638457, ainda vou monitorar para ver se tem alguma novidade.

Ah, mas vou usar o VirtualBox enquanto isso.

Seria bom se isso fosse simples. Mas, parece que o bug também afeta o VirtualBox: https://www.virtualbox.org/ticket/19644

E agora??? Como rodar as máquinas virtuais??

Por hora, a solução é permanecer na versão 5.7 até que uma correção saia. Qualquer novidade publicarei aqui.

Tenham uma boa semana.
