The symptom is the same (drive stops talking), but after a while rather than immediate.Yep.That suggests there might be some issue with what memory gets allocated or something?Or translated. Maybe it grooks due to being fed with an invalid bus address where it can't DMA do. 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?
