Bug 165950 – DMA doesn't work on acer aspire 9410 with ICH7 chipset (82801G)

• Product: Gentoo Linux
• Status: VERIFIED DUPLICATE

[Description Ewoud Canniere 2007-02-08 17:46:58 UTC]

I'm not able to set DMA on my acer laptop:
http://www.acer.be/acereuro/page9.do?sp=page4&dau34.oid=16773&UserCtxParam=0&GroupCtxParam=0&dctx1=2&CountryISOCtxParam=BE&LanguageISOCtxParam=nl&ctx3=-1&ctx4=BeLux&crc=3210271537

I tried selecting:

CONFIG_ATA_PIIX => DMA doesn't work
ATA_PIIX under the experimental drivers => DMA doesn't work
PATA_OLDPIIX => DMA doesn't work

it's a bothering problem because everything goes really slow especially fs checks.

I asked to some people and they said it would be fixed in the 2.6.19 kernel (i was on 2.6.18 than.) but still it doesn't work.

Reproducible: Always

Steps to Reproduce:
1. Compile new kernel
2. Reboot
3. See that it doesn't work :-)

Actual Results:  
DMA doesn't work, i even can't play a movie in a descend way.

Expected Results:  
See hdparm -d 1 /dev/hda work
