Tejun, Alan, Everything works when I disable the USB in the bios settings. I was also able to remove the irqpoll kernel parameter after turning off bios USB. The particularly interesting thing is that the USB mouse still works, as does a USB 2.0 drive I have connected. The Compact Flash drive at /dev/sda works fine, and the connected SATA drive works as well, though I need to do some testing to see how well these devices are performing. Using the irqpoll also made things work except for once. In that case, I got the same errors, delayed bootup, and missing SATA drive. Is there a new "hdparm like" tool for working with the new drives/drivers to be able to read/set parameters, run various tests, etc? This motherboard is an IBT MB899 mini-ITX. Thanks for the guidance with this! C. W.
