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. Wright
