androidbusybox:notfound问题和sh:can'taccesstty;jobcon

线索一 ：

引用老外的一段话：

Job control will be turned off since your shell can not obtain a controlling terminal. This typically happens when you run your shell on /dev/console. The kernel will not provide a controlling terminal on the /dev/console device. Your should run your shell on a normal tty such as tty1 or ttyS0 and everything will work perfectly. If you REALLY want your shell to run on /dev/console, then you can hack your kernel (if you are into that sortof thing) by changing drivers/char/tty_io.c to change the lines where it sets "noctty = 1;" to instead set it to "0". I recommend you instead run your shell on a real console...

线索二：

还是老外的：

现象：触摸屏上是一张左上角为鸭嘴兽的图像，触摸屏上还有显示字母：android，然后就不动了，请教了一位同事，同事说android还没有启动起来，让看下logcat ，结果logcat 也不能看，启动logcat时显示：

unable to open log device "/dev/log/main"……

查看/sys/kernel/logger这个目录，

因为网友说有一个日志开关：

echo 1 > /sys/kernel/logger/log_main/enable
发现根本没有这个目录，

然后看启动信息，从其他网友的资料看到正常android启动时kernel启动信息里应该有这几行：

logger: created 64K log 'log_main'
logger: created 64K log 'log_events'
logger: created 64K log 'log_radio'
OK，我的启动信息里没有这几行，看来这个内核没有编译进去 log 支持，他**的，难道要我重新编译内核？
