    Hi,
      2.4.0-test9 failed to boot on my LX164 Alpha system; 2.4.0-test8 works
    fine.

      It looses interrupts in the IDE probes; it is a CMD646 controller and
    what appears to be happening is that it is getting the wrong IRQs; under
    2.4.0-test8 we see:

    Oct 7 18:19:57 tardis kernel: CMD646: IDE controller on PCI bus 00 dev 58
    Oct 7 18:19:57 tardis kernel: CMD646: chipset revision 1
    Oct 7 18:19:57 tardis kernel: CMD646: not 100% native mode: will probe
    irqs later
    Oct 7 18:19:57 tardis kernel: CMD646: chipset revision 0x01, MultiWord
    DMA Limited, IRQ workaround enabled
    Oct 7 18:19:57 tardis kernel: ide0: BM-DMA at 0x8000-0x8007, BIOS
    settings: hda:pio, hdb:DMA
    Oct 7 18:19:57 tardis kernel: ide1: BM-DMA at 0x8008-0x800f, BIOS
    settings: hdc:DMA, hdd:DMA
    Oct 7 18:19:57 tardis kernel: hdb: , ATAPI CDROM drive
    Oct 7 18:19:57 tardis kernel: ide: Assuming 33MHz system bus speed for
    PIO modes; override with idebus=xx
    Oct 7 18:19:57 tardis kernel: hdc: IBM-DPTA-373420, ATA DISK drive
    Oct 7 18:19:57 tardis kernel: hdd: MATSHITADVD-ROM SR-8582, ATAPI CDROM
    drive
    Oct 7 18:19:57 tardis kernel: ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
    Oct 7 18:19:57 tardis kernel: ide1 at 0x170-0x177,0x376 on irq 15

    On 2.4.0-test9 I can't easily get a log saved; however it looks like its
    saying that both ide0 and ide1 are on irq 21 and then complains that it is
    loosing them.

    It is not unusual for PCI devices on Alpha to have IRQs > 16 (indeed my
    ether is on 17).

    .config on request for anyone interested.

    Dave
