为何android不停重启？大家帮忙看看(已解决)

我在一块开发板上运行android，android的主界面可以出来，但是，经过一个不确定的时间后，必然又重新回到redeye来回晃动的界面。而且点击触摸屏界面也必然马上回到redeye状态， 用am手工启动Java程序，也必然回到redeye状态。

以下是在串口上的输出，高手指点一下阿。。。

我感觉是system_server不知道什么原因被干掉了，所以导致其他的一些进程，如，zygote ,runtime,和java应用也被干掉，然后就这样不断重新启动。 但是system_server为什么会被干掉呢？

终于解决这个问题了，是因为framebuffer越界导致segment fault错误引起的。
但现在发现我板子上跑的android好慢啊。linux可以达到622.59 bogomips，cpu是pxa300的。 为什么会这么慢呢？
