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

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

Is there a patch for this?

Many thanks,
