Espero que este seja o lugar certo para isso. Comecei a receber falhas de sistema aleatórias que exigem ao jogar o dota 2 no Linux mint 17.3 rodando drivers nvidia. Isso aconteceria depois de alguns minutos de jogo - a tela congela e a última fração de um segundo de loops de áudio e o sistema não responde, exigindo uma reinicialização total.
Na época, achei que poderia ser uma falha de hardware, já que era uma máquina bastante antiga que eu estava planejando fazer upgrade de qualquer maneira. Então acabei adquirindo uma nova mobo, cpu e ram (Gigabyte GA-H170N-WIFI, Intel Core i5 6500, Corsair Vengeance LPX CMK16GX4M2A2133C13 16GB (2x8GB) DDR4) e mantive o mesmo GPU (GTX 750 Ti). Eu ainda estava recebendo as mesmas falhas. Eu então tentei o seguinte, nenhum dos quais teve qualquer efeito:
SSID diferente com instalação do sistema operacional nova - mesmo problema Neste ponto, acho que uma falha de hardware é descartada, já que é um sistema inteiramente novo.
Atualizando para o Linux Mint 18 beta
Eventualmente, percebi que, se eu seguisse o log do kernel enquanto era ssh'd de outra máquina, eu poderia ver o erro (no entanto, ele não estava nos logs após a reinicialização). Isso é o que eu estava recebendo:
