I think I can confirm this problem but give not so much informations. I had a 1200 Mhz Athlon running on a board with a onboard-controller and a promise udma 100 controller. I connected my dvd-write to one of these controllers, I don't know which anymore and I had corrupted data too, the system had nearly no load and I would guess that I had perpahs 5 places on a dvd which where corrupted. I used dma. The writer and the cable worked fine in a system with a dual-p3 with intel bx chipset. I think I was running a 2.4 kernel, newer than 2.4.20 I think. I currently got this system offline because I am moving. If you need more informations I will perhaps be able to gain them in a week or so. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
