Salve a tutto il forum.

E' il mio primo post nel forum; anche se sono un felice utente gentoo da diversi anni ho sempre letto il forum e risolto i problemi di configurazione senza aver bisogno di rivolgere quesiti, ma questa volta non ci sono riuscito nonostante le ricerche fatte.

Il mio problema e' questo: ho una installazione in cui gira un kernel 3.7.10 ed uso KDE come desktop manager. Ho da tempo iniziato ad usare networkManager per configurare la rete insieme al widget in kde.
Da quando sono passato al kernel 3.7.10 pero' non riesco piu' a creare la VPN che uso quando lavoro da casa; la VPN e' basata su pptp.

Escludo problemi di configurazione della lan perche' se avvio il sistema col kernel 3.2.12 tutto funziona perfettamente.

Ho configurato il kernel 3.7.10 partendo dal .config del 3.2.12 tramite un "make oldconfig"; se controllo le opzioni relative al PPP difatti risultano uguali nelle due configurazioni ma poi il 3.7.10 mi da errori.
Quando avvio la VPN dal /var/log/messages ho i seguenti messaggi:

Code:

Sembra che pptp non riesca a ricevere il reply del primo messaggio 'Start-Control-Connection-Request' andando poi in timeout. Ma esattamente la stessa configurazione funziona quando avvio il kernel 3.2.12 facendo correttamente l'autenticazione.
Qualcuno mi sa indicare quale puo' essere il problema?

Vorrei usare il kernel 3.7.10 perche' ho una buona stabilita' con il modulo brcmsmac per la mia scheda wireless, mentre non riesco in alcun modo a compilarlo nel kernel 3.2.12 (e anche questo per me e' un mistero che non sono riuscito a risolvere), perche' non riesco a rendere visibile la relativa opzione tra i possibili drivers dei moduli quando faccio girare "make config" per configurare il kernel.

Ringrazio fin d'ora per ogni suggerimento.
