ERRO do Kernel do Ubuntu 16 (“Oops: 0000 [# 1] SMP”) relacionado a amdgpu [closed]

Question

Eu instalei recentemente o Ubuntu 16.04 no meu notebook pessoal (Dell Inspiron 5548) e toda vez que eu tento sair de qualquer conta de usuário, recebo uma mensagem do Kernel BUG ("Oops") relacionada ao amdgpu.

Eu tentei atualizar a partir de 14 LTS e instalação completa usando uma imagem 16.04 na unidade usb. Eu também tenho usado o Ubuntu 15 no meu computador por um bom tempo sem problemas semelhantes.

Eu li que isso pode estar relacionado às novas placas gráficas e à substituição do fglrx e que apenas placas gráficas novas seriam suportadas. No entanto, eu instalei o Ubuntu 16 no Dell Studio 1458 (não me lembro da placa gráfica agora, mas também é Radeon) e funcionou como um encanto.

O relatório do BUG segue abaixo. Alguém sabe alguma correção para isso?

EDIT: minha placa gráfica é AMD Radeon ™ HD R7 M265.

Answer 1

Seus sintomas são os mesmos que os erros relatados aqui:

link

Você pode entrar na barra de lançamento e clicar no link "isso também me afeta" no bug acima, se você quiser chamar mais atenção dos mantenedores.

Até que o bug seja corrigido nos pacotes do kernel do Ubuntu, tente usar os pacotes do kernel 4.6, conforme sugerido por Renê Barbosa. Você pode baixá-los aqui:

link

Faça o download e instale os seguintes arquivos:

• linux-headers-4.6.0-040600rc7_4.6.0-040600rc7.201605081830_all.deb
• linux-headers-4.6.0-040600rc7-generic_4.6.0-040600rc7.201605081830_amd64.deb
• linux-image-4.6.0-040600rc7-generic_4.6.0-040600rc7.201605081830_amd64.deb

(Desculpe, não posso postar links diretos para os arquivos por causa das restrições de reputação do askubuntu)

    

Answer 2

O mesmo problema aqui. Usando a mesma placa gráfica.

EDIT: Consegui consertar instalando os últimos pacotes do kernel 4.6 do repositório mainline. Parece que algo precisa ser backported para o kernel 4.4 padrão do Ubuntu 16.04.

    

Answer 3

Eu vejo você atualizou o kernel e resolveu seu problema. Eu tenho as mesmas especificações e atualizei para o kernel 4.6 e agora o DRI_PRIME = 1 glxgears funciona bem.

... mas rodando jogos com o comando DRI_PRIME = 1 me traz o mesmo resultado (ruim) que correr com o cartão integrado. É normal ou sinto falta de alguma coisa?
