Ok, I have gathered much informations as possible that could help you.

I've tested different versions of linux as follows. None works fine but
all have different error messages:


With kernel 2.6.8.1 and kernel 2.6.9 I get continually apic error
messages that makes the kernel unusable for me:

May 28 13:12:53 orclex kernel: APIC error on CPU0: 60(60)
May 28 13:13:05 orclex last message repeated 44 times
This is repeating every few seconds.



Kernel 2.6.10
-------------

I did not recognize the error message above with apic error but I get
every 2 seconds the following message on my terminal which makes the
kernel unusable for me too.

Kernel 2.6.11.11
----------------

Kernel 2.6.11.xx is the first kernel where the message "drive appears
confused" is thrown.
I also recognize the following lines in syslog where the kernel hangs
for some seconds (nearly a minute) while booting:

May 28 13:47:10 orclex kernel: ACPI: PCI interrupt 0000:01:0a.0[A] ->

May 28 13:47:10 orclex kernel: hda: DMA interrupt recovery

I have enabled "ACPI APIC" in my bios. Disabling this causes the kernel
to hang on the last message above and repeating "hda: lost interrupt"
continually.

The "nobody cared" message is still here.

Some more informations like "packet command error: status=0xd0" but
still the same errors like kernel 2.6.11.xx.

To test the hardware if it is busted I've have installed an ugly redmont
os and I could not recognize any problems. I also have burned a cdrom
with my burner that is hdb on linux and makes the problems. So I think
the hardware can't be busted and there has to be a problem with the
module for the Intel Corp. 82801FB/FBM/FR/FW/FRW (ICH6 Family) IDE
Controller?

That would be very great. I would like to give you any more information
that is needed.
