Can you try changing include/linux/libata.h:
-#undef ATA_DEBUG /* debugging output */
+#define ATA_DEBUG /* debugging output */
and see what happens as it nears failure? The difference for me is ATA
(fails) vs ATAPI (works) for the DVD drive - but they follow essentially
the same code path. But if you're getting some disk IO, then there has
to be more to it than that.
Also, does swiotlb=0 make any difference?
