    I have exactly the same problem on -rc5 and it causes all I/O to stall
    periodically if I do _anything_ I/O intensive.

    On my box, I have 4 sata_nv handled SATA ports, with two pairs of different
    drives (two Maxtor, two WD) and it happens randomly on both. So it's
    absolutely nothing to do with the drive make/model.

    I'll try Jeff's suggestion of disabling ADMA now, but I think something more
    radical than this workaround should make it into 2.6.20 final, otherwise a
    lot of people are going to have broken boxes.
