Laptop se cuelga despues de un rato
Hola gente:
Hace un par de meses que estoy experimentando problemas con Debian
Sid/Experimental para amd64. Leyendo el /var/log/syslog me encuentro
lo siguiente:

Con una lectura rapida, me encuentro con unos "out of memory" y
tambien se ve que se come toda la swap.
Estoy usando el kernel 2.6.26-2-amd64.
Esto pasa generalmente cuando estoy usando iceweasel como navegador.
Si alguien sabe de esto o si es un bug, avise :)
Un saludo
