AHCI driver heads-up

[Matthew Dillon]

    I corrected a really stupid programming error yesterday that I had
    made in the AHCI driver.   Logical block addresses were not being
    translated properly for non-NCQ I/O, resulting in disk corruption for
    disks larger then 250G.  Generally only disks behind a port multiplier
    are affected.

    The bug has been fixed.  Everyone using the new AHCI driver, and
    particularly anyone using it with a port multiplier enclosure, should
    update.

    The SILI driver had the same bug (also fixed) but since it can run NCQ
    commands to targets behind a PM it is unlikely that anyone was affected.
    Still, people using the new SILI driver should also update.

    The SILI driver passed its 10-TB test.  The AHCI driver is undergoing
    a 10-TB test now and has passed so far.  The test still has 3+ days
    of run time to go.
