I will run memtest86 very soon. But in the meantime my computer just crashed.
The logs are presented below (I know that the module nvidia is loaded, but I 
never have problem with it before.).
I remark that a general protection fault occur, and I saw a lot of them 
recently (see also the second log trail for another error 2 hours earlier).

I also had these logs just before another crash. I see a "scheduling while 
atomic" does it seems it will be a kernel bug ?
