usb-storage: -- transport indicates command failure

[pinguin]

Ciao a tutti,
ho notato un problema relativo alla directory /var/log ed in particolare ai files syslog, debug e kern.log.
Tutti e 3 si riempono di stringhe come le seguenti:

Ne allego solo una piccola parte ma in effetti queste righe vengono ripetute all'infinito nei tre file di log che diventano enormi in poco tempo.
Qualcuno sa darmi spiegazioni su questo usb-storage: -- transport indicates command failure
che sembra essere la causa di tutto
preciso che attualmente non ho niente collegato a porte USB

utilizzo Ubuntu Edgy 6.10 versione a 64bit

Armati di pazienza... http://www.google.it/search?hl=it&q=usb ... erca&meta=

[pinguin]

cerca di essere meno criptico ???
in quella ricerca, come in quella simile che ti assicuro avevo già fatto inserendo l'oggetto del topic, trovo un gran numero di pagine che mi sembra segnalino solo problemi simili al mio, non mi sembra di vedere soluzioni.
mettimi almeno sulla strada giusta con qualche indicazione in più

P.S.: perchè lo hai spostato? è forse un problema specifico dei 64bit?
ciao

No, ma siccome esiste una sezione per i 64bit e hai un sistema a 64bit...

[pinguin]

sul problema, che è quello che mi interessa, mi sai dare qualche indicazione?

sullo spostamento: se non è specifico dei sistemi 64bit credo non fosse necessario spostarlo; la sezione generale ha più visibilità e forse qualcuno che non usa i 64bit ha avuto un problema simile e lo ha risolto; qui sembra un problema limitato a chi usa sistemi a 64bit per cui gli altri non lo considerano

Questa la parte di kernel che interessa quell'errore:

Codice: Seleziona tutto

	/*
	 * If we have a failure, we're going to do a REQUEST_SENSE 
	 * automatically.  Note that we differentiate between a command
	 * "failure" and an "error" in the transport mechanism.
	 */
	if (result == USB_STOR_TRANSPORT_FAILED) {
		US_DEBUGP("-- transport indicates command failure\n");
		need_auto_sense = 1;
	}

è probabile che non sia realmente un problema...
Inoltre... ma hai attivo il debug? Perchè le righe che vedo sembrano generate da debug...

credo in effetti che il debug su USB sia attivo nel Kernel

comunque tu ritieni non sia realmente un problema?
grazie

Questo è quanto sembra dal commento presente nel codice... prova a disabilitare il debug e vedi se continua a dare errore
