The better (and persistant) solution would be to check your hardware. As
long as all your drives, cables and chipsets conform the IDE specs, the
kernel wouldn't switch off DMA etc.
I have seen many cheap PCs, especially the one sold by companies like
"MediaMarkt" (a big store in Germany, "specialized" on technical stuff
like fridges, microwaves, TVs and PCs), with overlong IDE cables, which
tend to cause this errors very regulary.
Windows-Users don't see those errors, but everyone using a non-M$-OS gets
bitten by those bugs quite often.
