Na pocitaci mam pripojene 2 disky IDE na jednom je os druhy som pripojil az teraz ale nemozem na nom zapnut DMA viem ze sa to uz preberalo

Distro gentoo

Hlavny disk hdc problemovy hdd
tu su vypisi

      Pozri sa na config beziaceho kernelu, ci daco zaujimave nenajdes
      zcat /proc/config.gz | grep VIA
      zcat /proc/config.gz | grep DMA
      while (2*2 == 5) { echo "If you're reading this, something is definitely wrong"; }

        Tak mohol by si nas zoznamit trosku z tvojou zostavou...

        Kedze distro je gentoo predpokladam ze si jadro kompilujes sam.
        Tak ja ti odporucam komplet zakomentovat < >ATA/ATAPI/MFM/RLL support v jadre
        a nechat len podporu <*>Serial ATA (prod) and Parallel ATA (experimental) drivers
        a tam povolit <*>VIA PATA support. Viem je to len experimental ale ja to uz urcitu
        dobu pouzivam a zatial ziadny problem.

        Zmena bude asi taka ze prestanes pouzivat stare drivers a vyskusas nove(experimental)
        Ak ani tam nepojde UDMA tak mas problem :D

        P.S. poznamka je potom potrebne zmenit v zavadzaci OS (grub/lilo) root=/dev/hdx
        na root=/dev/sdx kedze potom sa aj PATA disky tvaria ako SATA/SCSI.
        a CD/DVD mechanika budu v /dev/sr0 (nezabudni preto <*> SCSI CDROM support).

        BadCRC, aky mas kabel?

        ake mas disky? podla relativne centralizovanej databazy znalosti by to malo chodit:
        http://hardware4linux.info/component/15857/
        i ked netusim ci mas akurat dosku od msi.

      Uz som to poriesil ale ked DMA a zvisne veci zapnem na disku tak ked zacnem kopirovat rozbehne sa to krasne na 25MB/s ale po paru sekundach mi rychlost klesne a potom mam zase dma a spol vypnute neviete ako to poriesit ??

        presnejsie hdparm /dev/hdd

        /dev/hdd:
        multcount = 0 (off)
        IO_support = 1 (32-bit)
        unmaskirq = 1 (on)
        using_dma = 1 (on)
        keepsettings = 0 (off)
        readonly = 0 (off)
        readahead = 256 (on)
        geometry = 38913/255/63, sectors = 625142448, start = 0

        po chvili kopirovania
        hdparm /dev/hdd

        /dev/hdd:
        multcount = 0 (off)
        IO_support = 0 (default 16-bit)

          skusil si vymenit kabel, iny bios, ...?

          bud mas problematicky chipset (hoci aj koli biosu) alebo je hnily kabel. alebo sa snazis nastavit iny mod DMA ako je povolene pri danom type kabla. skus (m/u)DMA33. pri 66 alebo vyssie potrebujes 80 zilovy kabel ktory nema mechanicke poskodenie (obcas sa na to zabuda, mierne zalomenie si malokto vsimne).
