With recent ide patches, the ide driver seems to try to use DMA mode even for a drive
which dosen't support it. CONFIG_IDEDMA_PCI_AUTO is enabled but even so with the stock
kernel this dosen't happen. older patches didn't have this behavior either. Is this
change intentional ?

This may not be a major problem, as nobody probably uses such an obsolete drive
nowadays.
