    > Hi all,
    > Just today I saw the commitments to /dev/ata src for releng 5_2 and rebuild kernel ( custom ) and the system which was working fine for few days, lockup in a few hours with WRITE_DMA error on LBA XXX .. the disk is attached to ICH5 SATA controller and build raid with atacontrol ( but in bios raid its disabled ). As somewhere I saw , it's recommended to disable hyperthreading and now I am running with disabled. My mb is Asus P4P800 deluxe

    Hi Putinas,

    I can't offer you any help but at least I can tell you that I'm
    experiencing exactly the same two problems: TIMEOUT - WRITE_DMA
    when hyperthreading is enabled and inability to reboot or power
    off when hyperthreading is disabled. My hardware is similar to
    yours: Asus P4C800E Deluxe with P4 3.0 GHz using the onboard
    SATA controller integrated into the ICH5. My hard disk is a
    WD Raptor 740GD. Currently nobody seems to take care of this
    problem although there must be quity a lot of people out there
    running into similar troubles.

    Regards,

    Alexander Mueller
