Ciao,

ho installato da un paio di mesi gentoo sul nuovo portatile.
Utilizzo pochissimi pacchetti in beta.
Ho già avuto 3 freeze improvvisi che mi obbligano a spegnere violemente il PC.

Esiste un modo per debuggare questa problematica?
Ho controllato le temperature e non ci sono problemi anche perché tengo sempre il pc sollevato e il core i5-2410 che ho scalda pochissimo.

Pensavo che i freeze fossero imputati a libreoffice, poiché i primi due si erano verificati quando avevo quell'applicativo aperto.
L'ho disinstallato e ho utilizzato openoffice.

Stamattina si è però riverificato il problema senza avere aperto né libreoffice né openoffice, ma con:
Skype
Firefox
Thunderbird
3 konsole
forse chromium (non sono sicuro)


il mio emerge --info

qualche problema c'era.
Hai cambiato kernel ultimamente?

Mia personale esperienza: il portatile si schiantava a piacere e non riuscivo a venirne a capo poi ho tolto il primo banco di ram, ho messo al suo posto il secondo e ... niente piu crash sino ad oggi (alla fine li ho cambiati tutti e due).

Almeno inizia con un memtest. Attenzione alle "nuove" opzioni del kernel per memory clean, move e quant'altro.

E' il primo kernel che praticamente utilizzo.

allora è probabile che ci sia qualcosa che non va nella configurazione. Prova a partire da quella di genkernel.

Controlla anche che gli headers non siano più recenti del kernel e, sempre nella configurazione, gli spazi di memoria riservati.

Bada che alcuni messaggi per "memory error" possono anche venire da un cavetto di connessione od alimentazione dell'hd allentato.
