Eu tenho tido problemas com um laptop em particular por várias semanas. Outro com o mesmo sistema operacional e atualizações está funcionando bem (então estou pensando que isso é um problema de hardware). O sistema parece travar quando eu faço muita atividade IO (como copiar um arquivo ou qualquer tarefa intensiva da CPU). Ele não parece voltar à vida a menos que eu reinicie o computador. Eu originalmente pensei que era um problema com o firefox ou cromo e, em seguida, o flashplayer. Uma vez que eu matei o firefox ou o cromo, meu computador se tornaria responsivo novamente, mas acabaria parando de responder novamente.
Eu vejo isso no dmesg:

Parece que talvez eu tenha alguma memória ruim - também o meu disco rígido está indicando que ele está no estado de prefail. Não sei se isso contribuiria ou não (duvido, pois todos esses programas já devem estar na memória).
Eu executei um teste de memória, memtest86, e não encontrei erros. A minha memória é ruim ou o que mais está acontecendo aqui? Eu quero saber o que está quebrado no meu sistema e se você tem alguma idéia sobre como corrigi-lo.
Parece que isso pode ser um bug do gnome-session / gnome-shell, já que tenho visto relatos disso ocorrendo no Fedora recentemente nos sistemas nvidia e ati. É peculiar que este problema tenha começado a acontecer logo no momento da atualização 3.2 e não ocorra em meu outro sistema executando este SO e versão também.
