Additional info: I am able to have machine install if I append acpi=off to kernel options. look at comment 2 for more details.
Because you are able to boot with acpi=off, it is unlikely that it is CFQ issue. Can you try elevator=deadline option on kernel options and see if install is successful or not (no acpi=off specified). If it is not successful, then it will more of less confirm that it is not CFQ issue but something else.
