Comment 345 for bug 272247

I've tried the following:

>If you have a custom DSDT, add "acpi_no_initrd_override" to the boot options. This
>- Then try the following combinations:
> * nohpet
> * idle=poll
> * acpi_skip_timer_override
>Do any of these make the boot work without a keypress?

idle=poll works on my machine. Boot is as fast as Hardy.
Fan speed is now proportionate to CPU temp again and CPU temps are back to normal.

Watching the boot process without boot options everything is fine until Setting preliminary keyboard.
At that point the keypressing is required.

An odd side effect are the entries in messages:
