    As always, the latest version of this driver is availalbe here:

    http://people.FreeBSD.org/~gibbs/linux/

    Complete CHANGELOG is now available at the above URL.

    I try to filter though LK as often as I can, but for
    best response, please email issues regarding this driver to
    me directly.

    Changes since 6.1.5 include:

            o Firmware generation is now a tunable option
              defaulting to OFF. Don't turn this on unless
              you really have a reason to re-agenerate the
              firmware (e.g. you are actively developing it).

            o aicasm Makefile changes from Alan Cox that
              attempt to make aicasm compilable on more
              distributions.

            o On some chips, at least the aic7856, the transition from
              MREQPEND to HDONE can take a full 4 clock cycles. Test
              HDONE one more time to avoid this race. We only want our
              FIFO hung recovery code to execute when the engine is
              really hung. This makes the aic7856 work again on systems
              affected by the PCI 2.1 retry bug.

            o Modify our interrupt handler so that optimizations
              that rely on level sensitive interrupts are disabled
              when edge triggered interrupts are in use. This
              affected the 284X and some EISA installations where
              level sensitive interrupts are disabled.

            o Staticize some rogue symbols. All exported symbols
              have either an "ahc" or "aic7xxx" prefix to avoid
              potential conflicts with other modules.

            o Fix the sorting of driver instances so that even
              if PCI devices are presented to the driver in a
              very strange order, it still works. In the past,
              we relied on function 0 of a device being seen prior
              to function 1. This should make the channel b primary
              BIOS option functional again.

            o Add a crude hack to make modunload/modload cycles work
              now that we are using the new PCI methods. We must
              detach our driver from each PCI device referenced by
              a call to our release method. The PCI code doesn't have
              a method to do this, so we muck with the pci_dev ourselves.

            o Deregister our PCI driver when aic7xxx_release releases
              the last host instance.

            o Only adjust our goal negotiation settings if the device
              is actually present. This prevents a disconnected lun
              that does not claim to support negotiations from messing
              up the settings for a successfully probed lun whose inquiry
              data properly reflects the abilities of the device.

            o Set the device structure as releasable should the inquiry
              come back with anything other than lun connected. We
              should also do this if the device goes away as evidenced
              by a selection timeout, but as we can't know if this
              condition is persistant and there is no guarantee that
              the mid-layer will reissue the inquiry command we use
              to validate the device, I've simply added a comment
              this effect.
