[pso] [SO2] Intrebare lab2

[Cosmin Ratiu]

Salut Eduard.

In primul rand, te rog trimite mailurile de acest gen pe lista pentru
ca sunt mai multi ochi care or sa vada mail-ul si raspunsurile vor fi
mai rapide si mai bune. In plus, poate le va fi de folos si altora
care s-au intalnit cu problema asta.

Despre problema: cred ca iti lipseste linkul /usr/src/linux catre
tree-ul de kernel pt care compilezi.

Cosmin.
