Subject: [2.6.8-rc1] lost DMA on my Intel 82801EB (ICH5) Serial ATA 150 Storage Controller

Hi,

Since 2.6.8-rc1, DMA does not work for me. I've tried (almost) all
kernels since that one: 2.6.8-rc[1234], 2.6.8.1 and 2.6.9-rc2.

With all of them I get the same result:

A hdparm -d tells me that DMA is off (and in fact, it is off as I can
see from the numbers of a hdparm -t).

And if I try to activate it with hdparm -d1, it gives me a "operation
not supported" error.

The last one that I've ben able to make DMA work is 2.6.7.

Attached is the output of:

* lspci -v
* hdparm -I /dev/hda
* /proc/cpuinfo
* cat /boot/config-2.6.9-rc2 | grep -i ^config
* dmesg (right after booting both 2.6.7 and 2.6.9-rc2)

Am I doing something wrong? Do I need to provide more information?

Many thanks in advance.

always cc: [email protected] on ATA stuff

you need CONFIG_BLK_DEV_IDE_SATA

ping Jeff Garzik to make it more verbose
(ie. add runtime warning)

OK.

That was it, it works now. The help message of that option confused me.

Thanks a lot.
