Using 2.6.18-rc4 and CONFIG_SCSI_SATA_AHCI=m, fails to detect ide cdrom.


03:00.1 IDE interface: JMicron Technologies, Inc. JMicron 20360/20363
Controller (rev02)

and from dmesg|grep -i ide

BIOS-provided physical RAM map:
ACPI: IRQ0 used by override.
ACPI: IRQ2 used by override.
ACPI: IRQ9 used by override.
Boot video device is 0000:01:00.0
Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2 ide: Assuming
33MHz system bus speed for PIO modes; override with idebus=xx Probing IDE

If i modprobe ahci dmesg shows:

ahci 0000:03:00.0: version 2.0

The BIOS sees the CDROM but it is not detected by ide driver.
