Oh I didn't even try yours, Andre's allready wouldn't work ...

I allready contacted Andre, the driver works swell on x86 Boxes ... :-(,
he said he couldn't help me any futher in the lack of a PPC to check
what's wrong.

The detection message from dmesg is:

Uniform Multi-Platform E-IDE driver Revision: 6.30
ide: Assuming 33MHz system bus speed for PIO modes; override with
idebus=xx
AEC6260R: IDE controller on PCI bus 00 dev 68
AEC6260R: not 100% native mode: will probe irqs later
AEC6260R: ROM enabled at 0x80810000
AEC6260: reg49h=0x00 ATA-66 Cable Port0
    ide0: BM-DMA at 0xf2000800-0xf2000807, BIOS settings: hda:pio, hdb:pio
AEC6260: reg49h=0x00 ATA-66 Cable Port1
    ide1: BM-DMA at 0xf2000808-0xf200080f, BIOS settings: hdc:pio, hdd:pio
hda: IBM-DJNA-352030, ATA DISK drive
ide0 at 0xf2000840-0xf2000847,0x000 on irq 23
hda: IBM-DJNA-352030, 19470MB w/1966kB Cache, CHS=39560/16/63, UDMA(66)

The first ide0 and ide1 detection look a little strange to me, as there is
only one drive connected to ide0 and the adress looks wrong aswell. The
second ide0 statement appears to be correct with 0xf2000840-847 ...

The Error messages look like:
 hda:hda: lost interrupt
hda: lost interrupt
ide_dmaproc: chipset supported ide_dma_lostirq func only: 11
hda: lost interrupt
ide_dmaproc: chipset supported ide_dma_lostirq func only: 11
hda: lost interrupt
 hda1ide_dmaproc: chipset supported ide_dma_lostirq func only: 11
[snip]
 hda6 hda7ide_dmaproc: chipset supported ide_dma_lostirq func only: 11
hda: lost interrupt
 hda8 hda9

For all nine Partitions on the drive. If I start pdisk /dev/hda I can read
the partition map (after a couple of seconds) and my /var/log/messages
file reads:
May 26 10:17:28 ma1304 kernel: ide_dmaproc: chipset supported
ide_dma_lostirq func only: 11
May 26 10:17:28 ma1304 kernel: hda: lost interrupt

ide_dma_lostirq func only: 11
May 26 10:17:38 ma1304 kernel: hda: lost interrupt

Just for completeness, the lspci -vvx reads:

Do you know what this is supposed to mean? Everything seems to work,
untill the kernel actually tries to access the drive. I tried ide0=reset
in the kernel options aswell as ide0=autotune. Didn't help.
