To be precise, I #defined both DEBUG and CMD_DEBUG. However, I am not sure the result is conclusive. On a good kernel I get a lot of lines of the type hda: dma_stat: 0x24 irq_stat: 0x44 mask: 0x04 hdc: dma_stat: 0x24 irq_stat: 0x5c mask: 0x10 and variations thereof. On a broken kernel the middle part changes to hda: dma_stat: 0x24 mrdmode: 0x00 mask: 0x04 Hope this is of any help, cu Martin - 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
