I'm running an ASUS A7A266 motherboard with an Athlon XP1700+ CPU and the linux-2.6.11-gentoo-r5 kernel though I have had the same problem with linux-2.6.10-gentoo-r6 linux-2.6.11-gentoo-r4 kernels. hda: Maxtor 6B200P0, ATA DISK drive 200 gb. The problem is that I cannot get DMA to work either during boot or after using hdparm. I'll place my dmesg and relevant .config lines in a moment. You will see that I do have the correct chipset selected and that it is built in, not a module. When I try hdparm it says that it has turned on dma however hdparm -t /dev/hda gives me results that are anywhere between 1/10 and 1/20 of the speed that I can attain with dma on this disk. If I run hdparm /dev/hda after running hdparm -t /dev/hda it tells me that DMA is no longer turned on. I tried to boot Knoppix (v3.7) from the CD, it booted into the 2.4 kernel and ran DMA without a problem, however when I tried to boot into 2.6 it just hung. I could see the hard drive L.E.D.S lit up but it would not boot 2.6 I have googled this problem to death and found alot of people having this same problem on various kernels going back to 1999 but not one solution for me. In searching through these forums I thought I had found the solution here : http://forums.gentoo.org/viewtopic-t-301098-highlight-m5229+dma.html "...hack drivers/ide/pci/alim15x3.c in order to bypass the checks for buggy revisions" despite the warnings about the possibility of losing my data I plowed ahead with the suggested hack. It didn't work, so I commented out the entire section, still no luck.

TSC cannot be used as a timesource. Possible reasons for this are: You're running with Speedstep, You don't have DMA enabled for your hard disk (see hdparm), Incorrect TSC synchronization on an SMP system (see dmesg). Falling back to a sane timesource now. I think that I have been pretty thorough and tried everything but have not had any success. Any help would be greatly appreciated. Reproducible: Always Steps to Reproduce: This happens everytime that I boot with the settup described above Actual Results: Several DMA expiry messages during boot No DMA after boot even when trying to set it with hdparm hdparm will say it is set after turning it on with hdparm -d1 /dev/hda but after running hdparm -t /dev.hda and then running hdparm /dev/hda it tells me that dma is off Expected Results: Faster boot time becasue I don't get timeout messages DMA to be working after I have booted hdparm to be able to turn dma on I think that I have been thorough but am open to the fact that I may have left out something crucial and of course would be happy to provide any information that would help to solve this problem.
Please test 2.6.12-rc2
I tried the 2.6.12-rc2 vanilla-sources and I can't even get them to boot - They give me a can't mount root error - I don't remember the exact error.
I tried applying this patch to ide-disk.c - http://www.mail-archive.com/linux-ide@vger.kernel.org/msg00744.html If you go back one message in the thread to: http://www.mail-archive.com/linux-ide@vger.kernel.org/msg00704.html The guy seems to be having the same problem as me. After applying the patch on the 2.6.11-gentoo-r6 I could no longer boot into that kernel. It was worth a try though.
S O L V E D The patch that I applied and reported below was supposed to be an improved version of this patch: http://www.mail-archive.com/linux-ide@vger.kernel.org/msg00704.html I am not sure why but the imporved one didn't work for me however after receiving a response to a forum posting that suggested teh original as opposed to the imporved patch I tried the original and it worked. I now have DMA. Can this be included in futre versions of the Gentoo-Sources? Thanks fo your help
Thats strange, as I think the patches should be functionally identical. Could you please try vanilla-sources-2.6.12_rc3 without patching it at all. If the issue is definately definately still there or you can't boot at all then I'll get in contact with the IDE maintainer.
I have applied the cleaned up version of the patch to 2.6.11-gentoo-r7 and it worked. The only difference that I can find is that the original when run gives an error message that a line unexpectedly ended. The cleaned up version has no error messages, it just works. I can only guess that when I ran this patch originally I did something wrong - I have no idea though what that mistake was though. I will try the vanilla-sources-2.6.12_rc3 this week for sure and report back. Thanks, Lanny
Included in gentoo-sources-2.6.11-r8
Daniel, Thank you very much. I appreciate your efforts. Its because of guys like you that I moved to Gentoo. Lanny
