This comes from the block layer, generic_make_request(), request is screwed up before it hits IDE layer.

Indeed, this is a lot more fun. ;)
Is this bug new/old?
Is it pdc202xx_old specific? Does the same havoc happen if you connect drives to the on-board Intel IDE controller?
Please post /proc identify data for both drives and PCI config space dump for PDC20267 so someone can verify them. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
