Hi

beginning with 2.4.21-pre1 the kernel disables DMA on my
regular ATA harddrives.

Upto 2.4.20 (Uniform Multi-Platform E-IDE driver Revision: 6.31)
there have never been any problems, now I get

! Uniform Multi-Platform E-IDE driver Revision: 7.00beta-2.4
  ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
! 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 vt82c686a (rev 22) IDE UDMA66 controller on pci00:04.1
      ide0: BM-DMA at 0xd800-0xd807, BIOS settings: hda:DMA, hdb:DMA

  ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
  ide1 at 0x170-0x177,0x376 on irq 15


Is there a patch for this?

Many thanks,
Helmut.
