Tested on up-to-date Dapper. Kernel: 2.6.15-26-386. The bug is still there. I observed the very same odd behaviour when I had Fedora so it seems a kernel issue. It's very annoying 'cause DMA is being disabled and performance highly decreases. I have two ST340823A disks and the bug is present in both of them.
