Processo kernel_task che occupa il 600% della cpu e rallenta tutto

Recommended Posts

Salve, da quando ho deciso di fare un'installazione "quasi" pulita di Lion sul mio MacBook Pro late 2011, (dico "quasi", perché della vecchia installazione ho voluto mantenere la mia cartella home), ho un problema che mi sta facendo impazzire: dopo qualche minuto di attività del sistema, (può bastare un salvaschermo), da Monitoraggio Attività, risulta che il processo kernel_task finisce per prendersi quasi il 600% della cpu, mettendo così in ginocchio l'intero sistema. Avendo appurato che non c'è nessun problema hardware di alcun tipo, voglio postare il log di sistema, nella speranza che qualche anima buona possa aiutarmi:

Reinstallare da zero e reinserire la cartella utente vecchia equivale a farsi la doccia e rimettersi gli indumenti sporchi.

Dovrai ripetere le cose nel modo corretto.

Il processo kernel task opera a basso livello, è uno dei processi fondamentali del sistema e rispecchia l'attività connessa al microkernel.

Per problemi temporanei in genere si risolve con un reset della PRAM.

Ritengo abbastanza inutile che tu la esegua, servirà a ben poco se non risolvi i tuoi problemi.

Anche se posso supporre che derivi tutto dal processo discendente coreaudiod.

Tra le disfunzioni spiccano Rogue Amoeba che confligge con AirFoil, ed è anche il motivo per cui è stata bandita da App Store.

Poi Awaken, una serie di estensioni per i browser, Safari e Firefox.

Ma ritengo inutile proseguire.

Fai una copia della cartella utente.

Installa dalla partizione di ripristino (Recovery) Lion, inizializzando il volume di destinazione.

1) Appena reinstallato, struttura il sistema utenti ex novo.

Crea un nuovo utente amministratore con lo stesso nome, nome breve e password di quello che avevi.

Crea un nuovo utente amministratore di scorta, crea un nuovo utente ordinario, non cancellare l'ospite già presente.

2) Scarica le applicazioni Apple eventualmente non comprese nell'installer.

Un browser se non usi Safari.

Installale, una per volta, aprile e verifica se almeno si aprono, girano e si chiudono normalmente.

Importa i dati e ricontrolla come sopra se aprono correttamente i dati.

Riavvia e controlla i tempi di spegnimento e riaccensione.

Fai il primo backup, se tutto va bene, preferibilmente con Time Machine.

3) Scarica ed installa, Java, Flash/Shockwave, Perian, Flip4Mac, Silverlight.

Apri e chiudi il browser, riavvia.

Scarica, ex novo dal web, ed eventualmente dai dischi le applicazioni professionali e quelle di uso corrente.

Solo una per ogni tipo di attività, successivamente metterai eventuali sovrapposizioni per usi particolari.

Se corrispondono ai requisiti attuali di sistema, installali uno per uno.

Ogni gruppetto di installazioni (4/5 di quelli più corposi) riavvia e testali, aprendoli, impostando di massima le preferenze e chiudendoli.

Fai un secondo backup

4) Scarica ed installa o trascrivi le applicazioni secondarie, testale e riavvia.

Scarica ed installa o trascrivi i client e le utilità, testali e riavvia.

Se tutto va bene, completa le impostazion.

Apri Preferenze di Sistema, Utenti e gruppi, e togli da Elementi del login tutto quello che non è strettamente necessario e voluto.

Installa TechTracker o AppFresh, fallo andare e ricordati di impostarlo automaticamente per il controllo giornaliero.

Fai un terzo backup dopo il riavvio.

5) Imposta ed esegui altre manovre, installa e modifica quel che vuoi, anche le cose un po' meno ortodosse.

puoi a questo punto modificare i default e fare del modding, sempre un po' per volta, prenditi due o tre settimane di tempo, un po' per giorno.

MA UNA PER VOLTA, lasciando del tempo tra una manovra e l'altra per testare il loro pieno e non problematico funzionamento.

Apri Preferenze di Sistema, Utenti e gruppi, e togli da Elementi del login tutto quello che non è strettamente necessario e voluto
