I had this happen once too. The reason was that i didn't compile the correct motherboard chipset in. Because of that, i also couldn't do a "hdparm -d 1" After i recompiled my kernel with the correct chipset support, all things worked ok. Use lspci to find out about your motherboard and the chipset it uses, then compile it in (not as a module). You'll also need to set: CONFIG_BLK_DEV_IDEDMA_PCI=y CONFIG_BLK_DEV_IDEDMA=y And, in my case, i needed CONFIG_BLK_DEV_PIIX But this last line will be different unless you have a PII.
