Oops po rmmod ide-scsi (powtarzalne kiedy załadowany piix)

[Radosław Kintzi]

Tak przy okazji. Pierwsza linia dmesga sugeruje, że nie potrzebuje 
ide-scsi, ale kiedy robię:
modprobe ide-cd dev=/dev/hda to dostaję informację, że nie ma takiego 
parametru dev. Zauważyłem
też, że nie mogę wypalać płyt cd-rw (cd-r jakoś idzie). Bliższe 
szczegóły podam w następnym mejlu.

ide-scsi is deprecated for cd burning! Use ide-cd and give dev=/dev/hdX 
as devic
