FWIW: I am running my Ultra 5 with a 120G WD IDE drive as the only disk drive
for a long time with weekly git-snapshot kernel and have seen zero problems for
a long time. Using DMA of course. Gcc has been what was in Debian unstable at
any point, currently 4.1. I just testbooted Debian's 2.6.18-4 kernel and it
works fine too:
