Linux kernel 2.6.28.10 failes when tried to mount JFFS filesystem

[Naveen Atmakuri]

 Hi All,

I am trying to boot Linux kernel 2.6.28.10 kernel on a board which is based
on ARM Cortex-A9. The tool chain that I am using is "Sourcery G++ Lite
2008q3-72". When I tried to mount the JFFS2 filesystem, kernel crash occurs.
Here is the dump of the crash.

It seems like the funtion "kernel_thread_exit" is causing the crash. But I
couldnot understand why this is happening. With the same kernel when I tried
to mount the NFS filesystem it works fine. Could anybody help me resolving
this issue?

Thanks in Advance,
