This causes problems on some VAIO notebooks - it seems like BIOS gets confused if APIC was turned on (particularly on my laptop when I try to reboot from Linux it hangs saying that thera problems with keyboard). That would be much better to have an option to turn it off in the boot options and not to recompile the kernel. Could somebody comment this please? Please CC me on this email address. TIA, Andriy
