No IDE interrupts... With the change reverted:
CMD646: IDE controller on PCI bus 00 dev 58 CMD646: chipset revision 1 CMD646: not 100% native mode: will probe irqs later CMD646: chipset revision 0x01, MultiWord DMA Limited, IRQ workaround enabled ide0: BM-DMA at 0x9000-0x9007, BIOS settings: hda:pio, hdb:DMA ide1: BM-DMA at 0x9008-0x900f, BIOS settings: hdc:pio, hdd:pio hdb: ATAPI CD-ROM DRIVE 40X MAXIMUM, ATAPI CDROM drive ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
IDE works again.
