The libata driver has copied the code from the IDE driver which caused a post 2.4.18 regression on many HPT370[A] chips -- DMA stopped to work completely, only causing timeouts. Now remove hpt370_bmdma_start() for good...
Do we need to move it rather than remove it though. I need to look at that a bit with my HPT370 and see what happens. I suspect that if we get a failed transfer we need to do the reset somewhere -
Well, the driver does the reset in hpt370_bmdma_stop(), and even twice.
perhaps qc_issue before anything hits the chip for the command ?
No idea. I think it's just not needed. MBR, Sergei -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
