Accessing CDROM drive in laptop SATA/PATA hardware config
Hello,
I have a Toshiba M40X-112 laptop.
So far I am quite happy with it, but the DVD-writer does not work.
I am getting loads of:
---snip---
Aug 6 13:39:01 satellita kernel: sr0: CDROM not ready. Make sure there is a disc in the drive.
Aug 6 13:39:32 satellita last message repeated 31 times

I have googled around and this problem comes up quite a few times.
Most remedies deal with older kernels and so far I cannot figure
out a way to make it work.
When I look at kernel messages, there is:

Aug 6 13:39:01 satellita kernel: sr0: CDROM not ready. Make sure there is a disc in the drive.
Aug 12 17:02:36 satellita kernel: ahci: probe of 0000:00:1f.2 failed with error -22
Aug 12 17:02:36 satellita kernel: ata_piix 0000:00:1f.2: MAP [ P0 P2 IDE IDE ]

Aug 12 17:02:36 satellita kernel: scsi0 : ata_piix
Aug 12 17:02:36 satellita kernel: scsi1 : ata_piix
Aug 12 17:02:36 satellita kernel: ata1: SATA max UDMA/133 cmd 0x000101f0 ctl 0x000103f6 bmdma 0x000118b0 irq 14

So for me it looks like the ahci module is giving up and ata_piix is
taking over.
lsmod prints out:
---snip---
Aug 6 13:39:01 satellita kernel: sr0: CDROM not ready. Make sure there is a disc in the drive.
sr_mod 17284 1

libata 116624 3 ata_piix,ahci,ata_generic
scsi_mod 137388 5 firewire_sbp2,sg,sr_mod,sd_mod,libata
---snap---
lspci shows:
---snip---
00:1f.2 IDE interface: Intel Corporation 82801FBM (ICH6M) SATA Controller (rev 03)
---snap---
kernel command line is:
---snip---
Aug 12 17:02:36 satellita kernel: Kernel command line: root=/dev/sda5 ro libata.atapi_enabled=1
---snap---
So I have tried this libata.atapi_enabled=1 option, but this doesnt
help.
Any advice?
Thanks Thomas
