Alguns dias atrás, o laptop decidiu fechar sem nenhum motivo relevante. A partir deste dia, ele cai aleatoriamente sem explicação.
Isso é o que eu (corretamente?) filtrou dos arquivos de log na última falha, mas não sei o que isso significa. No momento, há vários processos sendo executados: muitas páginas da Web no chrome e firefox, uma máquina virtual com o WindowsXP e o serviço clamscan.
Qual é a causa raiz do problema? Além disso, você acha que tenho que ativar o serviço apport para obter mais informações?

EDIT 1
Embora o anterior contenha todos os registros que I thougth eram relevantes para o travamento (inspecionando os timestamps), estes são os links para os logs completos
As falhas ocorreram 4 de novembro às 10:53:56 (na verdade, houve outra falha cerca de uma hora antes, mas não sei o timestamp correto porque não estava perto do laptop) .
Coisa estranha: você notou que há uma linha com um registro de data e hora diferente dos anteriores? Quero dizer isso

EDIT 2
Bem, tentei executar novamente um clamscan , dessa vez apenas dentro do meu diretório home . No entanto, em algum momento, um núcleo passou de 98 ° C, então parei o processo. Eu tentei executar clamscan novamente no modo detalhado para ver se havia um erro com arquivos específicos. Em algum momento, uma temperatura central ultrapassa 90 ° C, mas desta vez a área de trabalho se apaga e o computador para. Além disso, eu não fui capaz de reiniciá-lo por um tempo (até que ele seja resfriado novamente, eu acho).
Então, acho que o problema está relacionado com a alta temperatura dos núcleos. Certamente, clamscan congela meu laptop 3 vezes em 4 (e o único que não congela é porque eu forço manualmente a parada do processo).
Para as falhas anteriores, talvez algum processo em um certo ponto comece a aquecer os núcleos; no entanto, não sei qual processo.
FWIW, estes são os arquivos de log filtrados pelo tempo da falha do evento.
syslog kern.log
O padrão strange aconteceu novamente.
Alguma sugestão?
