Comment(by Quozl):

 SKU302 is the critical system for this bug to be fixed on.

 SKU292 and SKU299 are available to developers to test on.

 The memory part list for the three SKU was compared, with the result that
 SKU292 is representative for SKU302, and that SKU299 is unrepresentative.

 Testing can be done with SKU299 with kernel command line argument
 mem=1024K, but excludes one channel of the dual channel memory controller,
 and so experiences half the memory bandwidth.

 An SKU302 is to be sent to developers who do not have an SKU292.
