Hi Roy,
Just guessing here but seems you have SATA drives not IDE, don't
use/know much about SATA yet ;) but maybe this have something to do with
the error on activating DMA, from the logs your hard-disk *is* using
UDMA-133 & PIO4 ?
Could check BIOS-settings, other thoughts here? Check with 'hdparm'
setting on your hard (/dev/sdaX or /dev/....).
All kernel-config you show deals with IDE/ISA settings.
