Linux runs on ARM9 processor. The system works without any problem. It boots using uboot, mount filesystem and runs application program. Hovever, sometimes the file system becomes corrupt and it does not boot. In our application, we can not afford even a single failure. The logs are below. Could anyone tell me what was going wrong. Thanks.
