libata (piix) SATA hard drive and ATAPI cdrom

hi @all

first sorry for my english

my problem on my new notebook:

I use a custom kernel version 2.6.22.1
my harddrive is working well. it is a sata drive. The IDE interface is an Intel ICH8:

00:1f.2 IDE interface: Intel Corporation 82801HBM/HEM (ICH8M/ICH8M-E) SATA IDE Controller (rev 03)

dmesg said:

ata_piix 0000:00:1f.2: version 2.11
ata_piix 0000:00:1f.2: MAP [ IDE IDE -- -- ]

all right!
now it seems that my cdrom is not a sata device. so it it an atapi, right?
if I load the ide-cd module (incl. ide-generic etc) (I have to comile it as module - otherwise ---> kernel panic) dmesg said:

Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2
ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
ide0: I/O resource 0x3F6-0x3F6 not free.
ide0: ports already in use, skipping probe
ide1: I/O resource 0x376-0x376 not free.
ide1: ports already in use, skipping probe

so the sata driver blocks the interface.

I read that I should try a "libata.atapi_enabled=1" but now effect.
Another idea was to make a initrd and load the ide driver before the ata driver. But I don't want to use a ram disk.

is there a solution for my problem?

greets and thx

Re: libata (piix) SATA hard drive and ATAPI cdrom

You need to use the scsi cdrom module if you're using the sata subsystem.
If you compile it as a module it will be called sr-mod.

scsi cdrom support is allready compiled in the kernel.

Re: libata (piix) SATA hard drive and ATAPI cdrom

Hi there!

I have a ICH7 chipset laptop, and a similar issue with the new 2.6.22/2.6.22.1 linuxes.
Up to version 2.6.21.6, I could have both the IDE and SATA (the new one) stacks for the atapi dvd recorder and sata hard-disk respectively, without problems.
Using the old config, on the new kernels, gave me panics at boot.
Some googling led me to this bug report, that explained why I was having panics.
Seems that the IDE has precedence over SATA on boot.

I then compiled the IDE stack as a module, but the dvd recorder was unusable (even with all modules loaded ide-generic, ide-cd, etc).
So, what I did to solve the problem, was to remove _ALL_ the IDE stack, and compile the SCSI cd-rom module.

I can now mount, unmount, and read the dvd just perfectly.
The only thing left, is the burning feature.
I use gnome baker, and when I try to burn or erase a cd-rw, it goes to 99%, and just stays there. The app freezes and has to be killed.

Any ideas?

Thanks,
Quetzy Garcia

Re: libata (piix) SATA hard drive and ATAPI cdrom

My burning problem seems to only happen with Gnome Baker. The CD/DVD burning feature in nautilus, works flawlessly.
To answer grashalm, compile your kernel with SCSI CD-ROM support (as a module should be OK), and you should be just fine.

no, is is not fine.

i have open a bug report. it seems to be a problem with the ich8 map table.

You don't see an sr0 too? Then this sounds like a kernel upstream bug.

no sr0.

what does it mean?

Re: libata (piix) SATA hard drive and ATAPI cdrom

First configure ahci in the bios.

Then add "ahci" to MODULES in mkinitcpio.conf and make a new image (mkinitcpio -g image)
