各位大虾们：
最近想把xenomai实时补丁打到linux2.6.33上，然后移植到mini2440的板子上，为了保险起见，我先移植了没打补丁的linux2.6.33，移植是成功的，系统能顺利地挂载NFS根文件。可是当我打上补丁重新烧写的时候系统启动信息一直停在io scheduler cfq registered (default)这一句之后……然后就停止不动了……正常情况下（没打补丁的）之后会输出“Console: switching to colour frame buffer device 30x40”之类的信息。我不知道是不是补丁打错了，还是make menuconfig 之中的配置有问题……求教……下面是我打上补丁的启动信息
