Salve a TUTTI!
Ho un problema e non riesco a capire a cosa è dovuto. Quando sono nella schell in modalità testo mi compaiono i seguenti errori (vengono riempite anche molte schermate):

Code:

ide: failed opcode was: unknown
hda: task_out_intr: status=0x58 {DriveReady SeekComplete Data Request}
ide: failed opcode was: unknown
hda: status timeout: status=0xd0 {Busy}
ide: failed opcode was: unknown
hda: driwe not ready for command
ide0: reset: success
hda:DMA time_out error
hda: dma timeout error: status=0x58 {driveReady SeekComplite DataRequiest}

e:
Code:

hdc: dma_intr: error=0x84
                           {DriveStatusError Bad CRC}
hdc: dma_intr: status=0x51
                           {DriveReady SeekComplete Eerror}


La prima volta che questi errori mi sono capitati pensavo fosse l'HD che stava per tirare le quoia (a quel tempo avevo installato RedHat9); ma adesso ne ho provati ben 4 e con tutti mi compaiono le stesse scritte!

Vi domando quindi se è possibile che non siano gli HD ad avere dei problemi ma sia la mia scheda madre, e se fosse così posso essere tranquillo che non vada a rovinare gli HD (a volte sento pure degli strani rumori molto inquietanti)


Note:
*In Windows non compare alcun'errore ma forse questo è un altro discorso
*Il mio computer è un Pentium 2 350MHz

potrebbe essere saltato il supporto per il dma.

Se guardi il man di hdparm trovi sicuramente il flag per disattivarlo: a me sembra
Code:

# hdparm -d 0 /dev/hdc

poi rebootti e vedi se ti da gli stessi errori.

Hai compilato il chipset IDE giusto nel tuo kernel?

Quando usavo la RedHat 9 usavo un kernel standard e anche ricompilato.
Ora invece gli errori mi compaiono quando tento di installare gentoo dal lliveCD-universal

Disabilitando il dma non compaiono più gli errori quindi deve ci deve essere qualcosa di sbagliato nella configurazione del kernel suppongo

Problema risolto!
Bastava semplice aggiungere al kernel il modulo per chipset VIA82CXXX

Ossia per kernel 2.4.x
ATA/IDE/MFM/RLL support --> IDE, ATA and ATAPI Block devices -->
<*> VIA82CXXX chipset support

o per kernel 2.6
Device Drivers --> ATA/ATAPI/MFM/RLL support -->
<*> VIA82CXXX chipset support

Si, se non aggiungi il chipset giusto il dma non viene attivato e da errore
