Microblaze Linux 2.6.34 - 2.6.36 : Sysfs: Cannot create duplicate filename

Hi Everyone,

 

The following is the log of the linux kernel,

I have tested the following kernels:

-- Linux 2.6.34 from Xilinx git tree git.xilinx.com

-- again 2.6.34 from monstr.eu

-- Linux 2.6.36 main line kernel

 

And the following set of development tools :

-- EDK 11.5

-- EDK 12.1

-- EDK 12.3

 

In all of the cases the same thing as the following is happening and I can not understand what is the source of this problem.

In addition I am really getting disappointed from running Linux on Microblaze at all, because every day, that I decide to change the EDK version or the Linux version I will encounter strange bugs and problems that can be solved only by the main developers of the kernel themselves.

 

Do they have written the Linux kernel to be used by just themselves?

 

here is the log :
