   <para os="p1">GRUB has an issue where it sometimes doesn't detect
   the disk geometry correctly when used with Linux 2.6. This results
   in the error message <literal>Error 24: Attempt to access block outside
   partition</literal>. This patch also contains various fixes for raid
   controllers along with support for the new Intel Mac. Apply the
   following patch using the command below:</para>

    <para os="a">This package is known to have issues when its default optimization
    flags (including the <option>-march</option> and <option>-mcpu</option>
    options) are changed. If any environment variables that override default
    optimizations have been defined, such as <envar>CFLAGS</envar> and
    <envar>CXXFLAGS</envar>, unset them when building GRUB.</para>
