Package: linux-image-2.6.18-4-686
Version: 2.6.18.dfsg.1-12etch1
I'd installed a fresh Debian Etch on my PC. My motherboard is a ASUS P4PE with
ICH4 chip. Therefore the piix kernel driver was used.
On boot the right DMA modes are detected, but I get errors in the messages log.
With hdparm I'd setted DMA to 1. After media changes I get error messages, too.
And DMA mode was resetted to 0:
...

Because I didn't want a data loss, I removed the Etch kernel.
I downloaded the vanilla kernel 2.6.21.1 and build a kernel for my own.
The result was, there wasn't any error messages on boot, but the system freeze
on media change.
So I switched from piix to ata_piix. From this point (ata_piix with kernel
2.6.21.1) I didn't get any error messages and system freezes.
In my opinon either the piix drive in kernel 2.6.18 works right or it's a irq
conflict.
Is there a possibility to fix this error? I'd like to use the Etch kernel with
my system instead of compiling a kernel for my own...
