pandaboard linaro:request_suspend_state: wakeup (3->0) after reboot

android有时会遇到把自己制作的initlogo.rle放入 根目录下，第一次启动能够看到图片，第2次启动就有看不了，提示没有 initlogo.rle？

查看代码可发现，在system/core/init/init.c [load_565rle_image]--> logo.c中 ，显示完毕initlogo.rle之后作了 unlink 操作。该操作对于android默认的只读型system.img 是没问题,, 但对于自定义的yaffs 或者ubi形式的可读写型的system.img时就有问题了。会造成将initlogo.rle删除，下次启动时读取不到该文件。可以通过注释掉logo.c的load_565rle_image（）中的unlink（fn）语句来规避该问题。
