右，查了一下发现是"hardware interrupts"在占用（用proc explorer看的，task
manager会把它算在system idle进程里）。
google过，发现有种说法是SATA硬盘的驱动没有装好导致读写出错，使得硬盘工作在
PIO模式（正常的应该是DMA模式），所以出现这种情况。据说出6个还是3个错硬盘就会
自动从DMA转换到PIO. 可是我肯定驱动是装好了的（重装驱动也没用），硬盘用chkdsk
和lenovo的diagnoise软件测试过也没有任何问题，而且出问题的时候硬盘也还是工作
在DMA模式。
最奇怪的是如果把机器放在桌子上用，不移动的话，可以用很长时间（好几天）也不会
trigger这个问题。可是只要端着它走动一下的话（比如客厅到卧室），再使用就会很
快trigger这个问题。而且一旦Interrupts开始占用CPU，就不会停止。让机器Sleep一
下再打开可以使问题消失（只是有时过一小会又开始出问题，有时又可以正常很长时间
）。

发帖数: 256 | 4 读《Linux Kernel Primer》，上面写exceptions typicall happen after an
intruction's exectuion, and interrupt can happen in between instructions。
这里我不太清楚after an intruction's exectuion 和between instructions的差别。
难道是指的exceptions 是一个在取指令周期，取数据周期和执行周期都完成之后发生
，而interrupt 可以在这些周期之间发生？
请教高手，谢谢！ |

最后系统在这两个external interrupt上有多精确，跟有多少
同级和更高级的hardware interrupt有关，也跟你的ISR的复杂度有关。
不过一般系统都是external优先级最高，so，improve的办法是
1）用高时钟频率的芯片，
2）尽量减少ISR的时间复杂度。 |
