I'm still having problems with dma on the secondary channel of my
PDC20268. Channel 1 is ok.

# hdparm -Iv /dev/hdg| grep '*u'
DMA: mdma0 mdma1 mdma2 udma0 udma1 *udma2 udma3 udma4

# hdparm -X68 /dev/hdg

/dev/hdg:
setting xfermode to 68 (UltraDMA mode4)

(no errors logged)

# hdparm -Iv /dev/hdg| grep '*u'
DMA: mdma0 mdma1 mdma2 udma0 udma1 *udma2 udma3 udma4

There's no such problem w/ 2.4.20 vanilla.
