hdc: lost interrupt

Good evening, all. I've been trying to get 2.5.x to boot up without
losing IDE interrupts. I tried disabling multimode in makeconfig but to
no avail.

My IDE controller and chipset are as follows (via dmesg):

ide: Assuming 33MHz system bus speed for PIO modes; override with
idebus=xx
VP_IDE: IDE controller on PCI bus 00 dev 39
VP_IDE: chipset revision 6
VP_IDE: not 100% native mode: will probe irqs later
VP_IDE: VIA vt82c686b (rev 40) IDE UDMA100 controller on pci00:07.1
    ide0: BM-DMA at 0xe000-0xe007, BIOS settings: hda:DMA, hdb:DMA

...

Uniform Multi-Platform E-IDE driver Revision: 6.31
ide: Assuming 33MHz system bus speed for PIO modes; override with
idebus=xx
VP_IDE: IDE controller on PCI bus 00 dev 39
VP_IDE: chipset revision 6
VP_IDE: not 100% native mode: will probe irqs later
VP_IDE: VIA vt82c686b (rev 40) IDE UDMA100 controller on pci00:07.1
    ide0: BM-DMA at 0xe000-0xe007, BIOS settings: hda:DMA, hdb:DMA
    ide1: BM-DMA at 0xe008-0xe00f, BIOS settings: hdc:DMA, hdd:DMA
hda: QUANTUM FIREBALL SE6.4A, ATA DISK drive
hdb: ATAPI CD-ROM DRIVE 40X MAXIMUM, ATAPI CD/DVD-ROM drive
hdc: WDC AC36400L, ATA DISK drive
hdd: CRW6206A, ATAPI CD/DVD-ROM drive
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
ide1 at 0x170-0x177,0x376 on irq 15
hda: 12594960 sectors (6449 MB) w/80KiB Cache, CHS=784/255/63, UDMA(33)
hdc: 12594960 sectors (6449 MB) w/256KiB Cache, CHS=13328/15/63,
UDMA(33)

And /proc/pci reports my chipset as such:

  Bus 0, device 0, function 0:
    Host bridge: VIA Technologies, Inc. VT82C693A/694x [Apollo PRO133x] (rev 196).
      Master Capable. Latency=8.
      Prefetchable 32 bit memory at 0xd0000000 [0xd7ffffff].
  Bus 0, device 1, function 0:
    PCI bridge: VIA Technologies, Inc. VT82C598/694x [Apollo MVP3/Pro133x AGP] (rev 0).
      Master Capable. No bursts. Min Gnt=12.
  Bus 0, device 7, function 0:
    ISA bridge: VIA Technologies, Inc. VT82C686 [Apollo Super South] (rev 64).
  Bus 0, device 7, function 1:
    IDE interface: VIA Technologies, Inc. Bus Master IDE (rev 6).
      Master Capable. Latency=32.
      I/O at 0xe000 [0xe00f].

And I have the following IDE kernel setup for 2.5.6-pre1+xfs:

Has anyone else with a Via chipset been able to boot into 2.5.x without having these interrupt problems? Any suggestions will be helpful.

Thanks.
