+ * The following bug only affects older (XPC8245) processors.
+ * DMA transfers initiated by external devices get corrupted due
+ * to a hardware scheduling problem.
+ *
+ * The effect is:
+ * when transferring X words, the first 32 words are transferred
+ * OK, the next 3 x 32 words are 'old' data (from previous DMA)
+ * while the rest of the X words is xferred fine.
+ *
+ * Disabling 3 of the 4 32 word hardware buffers solves the problem
+ * with no significant performance loss.
