-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, with "acpi_apic_instance=2" I get APIC error on CPU1: 00(40) (with dmesg) - so I guess working better is with acpi_apic_instance=0. acpi_apic_instance=2I attached the output of dmidecode. By the way I have big problems with overheating and therefore shutting down, but I am not sure if that is related.
