SCSI cd emulation

[Vincenzo Di Massa]

Hi.
I noticed that the last 2.6.10-25 kernel detects my CD/DVD drives as scsi 
devices.
For some reason the system hangs on boot (before init startup) when detecting 
the cdwriter.

My question is the following: why is scsi emulation needed? Shouldn't it be 
avoided becouse it is buggy with 2.6.x kernels. How can it be disabled?
In the ide-scsi 2.4.x days I used hdc=ide-scsi in the kopts to enable it. But 
now I don't have it set and ide-scsi is popping up anyway.

I post this question here becouse:
1) If it is a bug I think ubuntu-dev is the right place (bug tracers... 
nhaaa!!)
2) If it is not a bug, I would like to know why ide-scsi got resurrected.

Regards, Vincenzo
