ata driver. - FreeBSD

Could there be problem in FreeBSD 5.x (specially in 5.4) ata driver that causes dma timeouts? mostly those problems in burning dvd-images that I was asking yesterday. because in some puter on same drives and all same hardware I had no problems on windows xp or linux 2.4-kernel... asking this because I had dma timeout problems on freebsd 5.3 puter too. it works fine with pio mode, but when I turn on dma it timeouts all the time. -- kpn IRCnet...

    Now after more test I found out that I can't even copy large files
    from that drive to another. It hangs on same 3.2GB then too. with dma
    timeout. so it has really nothing to do with dvd-burner drive nor
    atapicam.

    but when I set PIO mode it works fine.

    Try enabling DMA for ATA but *not* for ATAPI.

    Okay, sounds somewhat familiar.
    That code is undergoing extensive development.
    Soeren Schmidt has a set of patches for his latest set of upgrades,
    but they're not going into the main tree quite yet. http://www.freebsd.dk/

    I tried to use that patch (releng5 diif with 5.4-beta1) and after that
    kernel didn't compile anymore. stopped on atapicam compile.
