我有一台使用了一年的 Acer Aspire 4752G 上网本，运行 Kubuntu 12.04 LTS，安装了所有最新的发行版更新。
之前它运行得很好，直到大约一周前突然开始反复崩溃。
以前，在极少数情况下，它完全冻结，即使我无法按 Ctrl+Alt+F1 进入控制台，Alt+SysRq+r (eisub) 也能够相对正常地关闭所有内容并重新启动，但现在，即使 Att+SysRq 在冻结时也什么也不做。
最后一次坠机发生在今天（5 月 26 日）上午 10:40 左右（记录时间）。
我该如何开始解决这个问题？
这些是我从各种日志中识别出的亮点。

尝试禁用 ACPI，首先检查：
cat /proc/cmdline
如果未设置 acpi=off，则使用 编辑并/etc/default/grub更新，例如新条目应为：GRUB_CMDLINE_LINUX_DEFAULTacip=off
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=off"
重新加载 grub 配置：
sudo update-grub
然后重新启动。
