Right after boot, hdparm -d /dev/hda tells me DMA is off while hdparm -d
/dev/hdb tells me it's on.

Also the /var/log/syslog lines :

Nov 23 22:15:46 xp kernel: hdb: dma_intr: error=0x84 { DriveStatusError
BadCRC }
Nov 23 22:15:46 xp kernel: hda: DMA disabled
Nov 23 22:15:46 xp kernel: ide0: reset: success
