    It aint B7 specific nor ATA DISK specific, also happens on -RC1,
    sometimes on ATA disk (AD0) and a number of times on optical devices.

    About 20 minutes ago I have just tried -RC1 and a LiveCD built on top of
    RELENG_5_3 on 4 different laptops, Toshiba and Sony Vaio (both w/ DVD-R
    device) a "generic" transmeta based stuff and another Toshiba Satellite
    w/ combo optical.

    The 4 of 'em showed the same behaviour:

    acd0: TIMEOUT - READ_BIG retrying (2 retries left)
    acd0: TIMEOUT - READ_BIG retrying (2 retries left)
    acd0: TIMEOUT - READ_BIG retrying (2 retries left)
    acd0: TIMEOUT - READ_BIG retrying (2 retries left)

    and 10 minutes later the devices "fires" (READ_BIG.. device fired) and
    so, stalls
