This is with an ASUS A7N8X-E Deluxe mother board with Maxtor drives hooked to the SATA controller. Your default config with these kernels causes some type of driver conflict resulting in a Disk hang and failure to complete bootup. linux-ide list suggested that I don't include the siimage driver. I tried this but it didn't clear the problem.
I have successfully built and use 2.6.7 bk12 but if I apply your .config even with siimage removed it still won't boot.
Thanks Hubert
