Hello, I've seen these error messages too. And also WRITE_DMA TIMEOUT! You may have a hardware problem, but I'm not convinced. I had these messages on _new_ computers from time to time. After updating from 5.2 to 5.3, 5.4 it seems to have gone for me. But that's obviously not the case for you. I've read on a list to try to disable acpi, but that does not help. A collegue of mine sees this even with his dvd! I've had it with a plain ata drive (maxtor) using udma100 and with a promise ata raid controller (wd drives) at udma66. All _new_ hardware! I can't tell you if it is some 5.X specific problem. But the systems I am running under 4.11 never had these problems. Is there someone on this list with similar experiences? Norbert
