Titolo: Problema scheda scsi

Dopo essere passato dalla RedHat 7.0 alla 7.1 ho il seguente problema
possiedo un masterizzatore SCSI YAMAHA regolarmente riconosciuto al boot
(scsi0) <Adaptec AIC-7850 SCSI host adapter> found at PCI 0/12/0
(scsi0) Narrow Channel, SCSI ID=7, 3/255 SCBs
(scsi0) Downloading sequencer code... 415 instructions downloaded
scsi0 : Adaptec AHA274x/284x/294x (EISA/VLB/PCI-Fast SCSI) 5.2.4/5.2.0
       <Adaptec AIC-7850 SCSI host adapter>
  Vendor: YAMAHA    Model: CRW8824S          Rev: 1.00

la scheda scsi  %/1iso8859-15 una Adaptec AIC-7850 SCSI
ma sembra che abbia dei problemi, infatti questo  %/1iso8859-15 quello che trovo nel file di log

non riesco a masterizzare con cdrecord questo  e'  quello che dice
cdrecord: Input/output error. test unit ready: scsi sendcmd: retryable error

facendo cdrecord -scanbus dal file di log risulta:

mi potreste indicare cosa fare perche'  non ci capisco nulla
Grazie

Dunque mi pare di aver capito che il modulo aic7xxx sia buggato fino al
kernel 2.4.3 mi pare Infatti la RH7.1 usa la 2.4.2. Mi pare che lo letto
su LINUX&C ma forse stò dicendo un sacco di cazz..
Ciao

IO controllerei bene cablatura e alimentazione. Ha la faccia di essere piu'
un prb hw che sw.
