DVDRW drive and 2.6.12-1-em64t-p4-smp
Hi!
I have a problem with my DVDRW drive when using kernel
2.6.12-1-em64t-p4-smp. The SCSI emulation seems to be activated
and my system freezes when I try to burn a DVD. Here is the dmesg
output when executing "modprobe ide-generic" :
ICH7: IDE controller at PCI slot 0000:00:1f.1
ACPI: PCI Interrupt 0000:00:1f.1[A] -> GSI 18 (level, low) -> IRQ 18

The problem isn't present with 2.6.12-1-amd64-generic where SCSI
emulation seems to be deactivated and I don't have problem to burn
DVDs. Here is the dmesg output when executing "modprobe
ide-generic" :

What is the difference between the two kernels? Why one is with
SCSI emulation? Is it normal? What can I do to use
2.6.12-1-em64t-p4-smp without SCSI emulation?
Thank you,
Jean-François
