hallo,
nachdem ich nun von Slackware 9.1 auf Slackware 10.0 umgestiegen bin habe ich ein problem mit cdrecord. Und zwar folgendes:

Nach dem aufruf von cdrecord erkennt es erstmal meinen brenner richtig aber dann geht die systemlast auf 100% und ich kann erstmal für ein paar minuten nichts mehr am rechner machen. cdrecord liefert dazu aber folgende meldung:

Code:
cdrecord: Input/output error. read buffer: scsi sendcmd: no error
CDB:  3C 00 00 00 00 00 00 FC 00 00
status: 0x0 (GOOD STATUS)
cmd finished after 32.348s timeout 200s
Mh, ist das jetzt ein fehler oder nicht?
Aber irgendwann ist das warten dann zuende und cdrecord fängt mit dem brennen an! Die erstellt cd funktioniert dann auch fehlerfrei! Diese problem tritt sowohl mit der scsi-emulation und ohne auf.
Ich habe auch in syslog geschaut, da werden eine menge scsi fehler ausgegeben!
Hat sich denn an der scsi-emulation von kernel 2.4.22 (Slackware 9.1) zu 2.4.27 (Slackware 10.0) etwas grundlegendes geändert?

ich habe die ausgabe von cdrecord und den abschnitt aus syslog mit beigefügt, ich hoffe das mir da jemand weiterhelfen kann.
