ide, via, unnecessary probe?

Hello Alan, all:

To the first channel of my onboard via ide controller are attached no devices, only to the second channel. During boot, the kernel keeps trying to probe the first channel, as seen below, and delaying the boot unnecessarily:

VP_IDE: IDE controller at PCI slot 00:04.1
VP_IDE: chipset revision 16
VP_IDE: not 100% native mode: will probe irqs later
VP_IDE: VIA vt82c596b (rev 23) IDE UDMA66 controller on pci00:04.1

    ide0: BM-DMA at 0xd800-0xd807, BIOS settings: hda:pio, hdb:pio
    ide1: BM-DMA at 0xd808-0xd80f, BIOS settings: hdc:DMA, hdd:DMA

SiI680: IDE controller at PCI slot 00:0a.0
SiI680: chipset revision 2
SiI680: not 100% native mode: will probe irqs later
SiI680: BASE CLOCK == 100
ide2: MMIO-DMA , BIOS settings: hde:pio, hdf:pio
ide3: MMIO-DMA , BIOS settings: hdg:pio, hdh:pio
hda: IRQ probe failed (0xfffffdf8)
hda: IRQ probe failed (0xfffffdf8)
hda: no response (status = 0x0a), resetting drive
hda: IRQ probe failed (0xfffffdf8)
hda: no response (status = 0x0a)
hdb: IRQ probe failed (0xfffffdf8)
hdb: IRQ probe failed (0xfffffdf8)
hdb: no response (status = 0x0a), resetting drive
hdb: IRQ probe failed (0xfffffdf8)
hdb: no response (status = 0x0a)
hdc: SONY CD-ROM CDU5221, ATAPI CD/DVD-ROM drive
hdd: RICOH CD-R/RW MP7200A, ATAPI CD/DVD-ROM drive

This is with 2.4.21-ac1 and 2.4.19-24mdk.

hda=noprobe hdb=noprobe boot parameters solves the issue, but there should be some automagic to handle this more nicely. I can try any patches happily.

Best regards,
