 Nothing obvious... the disk seem to be detected properly. Do you have
 the support for mac partitions and the SCSI disk driver (BLK_DEV_SD)
 enabled ?

The PATA modules was built statically, and BLK_DEV_SD as a module (and
not included in the ramfs).
Now it boot correctly, many thanks.

Have a nice day

PATA/legacy IDE subsystem on PowerMac

2010-05-18 Thread JJDaNiMoTh 
Hello,

I hope I've posted to the right list.
I'm the maintainer of the linux kernel in ArchlinuxPPC [1].

We actually set statically the support for the PowerMac on-board IDE support 
(under ATA/ATAPI/MFM/RLL support (DEPRECATED) ), and the disk is recognized 
correctly (hda*).
If we try to remove this legacy support, enabling Serial ATA and Parallel ATA 
drivers -- Apple PowerMac/PowerBook internal 'MacIO' IDE (NEW) statically, 
the kernel doesn't recognize the partition on the HD. We tried different 
powerbook, and the result is the same.

Because we haven't log, I take two photos [2] [3].

With legacy stuff, I used hda6 as root device: with PATA, neither hda{5,6,7} or 
sda{5,6,7} work.
As you can see from the photos, seems that the hd isn't attached to any device 
under /dev.
With request I could upload somewhere the configs (working and not working) 
used, but they differ only for the things above.

Please let me in the right direction.
Many thanks to all.
