Reported by Chris Johns in Bug 1433:
We need to remove the SG alloc calls from the cache read code. The code
currently allocates a block of RAM on the stack with an array of pointers
to
the BD. I consider the array of size of 1 at the end of the struct and the
way
it is allocated as fragile code. The BD already contain a link node which
is
not used at the driver layer. It would be much better to use a chain to
hold a
list of BDs to fill.
