Perhaps the BIOS or ACPI tables are just defective. Those are "received illegal vector" errors, and they typically indicate hardware flakiness or BIOS issues. Could be inadequate power supply, inadequate cooling, a BIOS bug (please check for updates), a too new CPU (again, check for a BIOS update), or simply a poorly- designed mainboard. /Mikael - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
