Nouveau nv50cal

[CielitoLindux]

Salve a tutti.
Da qualche settimana lascio acceso il mio pc di casa (che monta Arch+lxde) acceso con emule attaccato.
Quando torno la sera e mi metto a guardare ciò che ho scaricato mi va quasi sempre in blocco dopo poco. Solitamente mentre guardo qualche film scaricato per vedere se è quello giusto, se è in italiano ecc ecc e quindi andando avanti e indietro col player (vlc o gnomepalyer) per verificare ciò. Ad un tratto mi va in blocco e solitamente mi tocca spegnere brutalmente. A volte però riesco a salvarmi e a vedere dentro dmesg:

Parrebbe proprio un problema con i driver nouveau. Ora è vero che il pc è vecchiotto (una decina d'anni) ma è pur sempre un 3.2 GHZ monocore con 3 GB di ram.
Scheda grafica e driver in uso:
