错误时间：initramfs里面的init里面的mountroot之前
ACPI: [Package] has zero elements
解决方法：CONFIG_ACPI_THERMAL设置为y

猜測 你的 硬件 或 Bios 需要檢測

1. 參閱

楼上的链接里有 [Package] Contains 13 Elements:
而我的提示里是说，zero elements。
我是直接拷贝的3.13.0-44-generic的配置文件修改的。
和硬件没关系，因为ubuntu14.04官方版可以正常引导。

下面的是我的配置文件的ACPI部分：
# CONFIG_PM_WAKELOCKS is not set


CONFIG_PM_TEST_SUSPEND=y



# CONFIG_WQ_POWER_EFFICIENT_DEFAULT is not set

# CONFIG_ACPI_PROCFS is not set

CONFIG_ACPI_PROCESSOR_AGGREGATOR=m
CONFIG_ACPI_THERMAL=m

# CONFIG_ACPI_PCI_SLOT is not set

# CONFIG_ACPI_BGRT is not set

CONFIG_ACPI_APEI_ERST_DEBUG=m
# CONFIG_ACPI_EXTLOG is not set

CONFIG_X86_APM_BOOT=y


下面的官方的不同的部分
# Power management and ACPI options
#



CONFIG_PM_WAKELOCKS=y
CONFIG_PM_WAKELOCKS_LIMIT=100
CONFIG_PM_WAKELOCKS_GC=y


# CONFIG_PM_TEST_SUSPEND is not set



CONFIG_PM_CLK=y
CONFIG_WQ_POWER_EFFICIENT_DEFAULT=y

CONFIG_ACPI_PROCFS_POWER=y

CONFIG_ACPI_PROCESSOR=y
CONFIG_ACPI_IPMI=m

CONFIG_ACPI_PCI_SLOT=y



CONFIG_ACPI_BGRT=y

# CONFIG_ACPI_APEI_ERST_DEBUG is not set
CONFIG_ACPI_EXTLOG=m

替换成官方的config文件的ACPI部分错误消失。

# CONFIG_PM_AUTOSLEEP is not set
# CONFIG_PM_WAKELOCKS is not set


CONFIG_PM_TEST_SUSPEND=y

# CONFIG_DPM_WATCHDOG is not set

a）autosleep不是一个必须的功能，可以通过CONFIG_PM_AUTOSLEEP打开或关闭该功能。
1）wakelocks功能不是linux kernel的必选功能，可以通过CONFIG_PM_WAKELOCKS开关。
