Package: linux-image-2.6-686-smp
Version: 2.6.15-6
Severity: important
Tags: patch

I recently installed a Pioneer DVD-RW drive (DVR-110D) on my PC and I
couldn't get it to write at full speed. Tried to activate DMA with
hdparm -d1 /dev/hda but got a message: "Operation not permitted".
I have a motherboard with Intel 865 chipset, one SATA hard drive
(/dev/sda) and the DVD drive.
I found that DMA support worked under Ubuntu 5.10 and Knoppix 4.0.2 and
after analyzing the logs and lsmod output realized that both distros
have ide-core support built in, so it started earlier in the boot process than in Debian where it is a module.
Tried to make it load before but didn't get it. I was just about to
recompile to test but thought about passing a parameter to the kernel to
force earlier loading. Passed hdc=cdrom, and although it didn't load
before libata this time hdparm worked and I could write at full speed.

I passed the patch tag because I found a workaround for the problem,
hope it isn't too wrong.

If you need more info I'm willing to help. Thanks in advance.

closing as if it was a kernel bug it is surely fixed in newer 2.6.24.
maybe an yaird bug, but no followup from initial report.
not worth to keep lying around.
