Hi Aravind.
If you are running libss7/chanss7 on 8260 proc with embedded linux, you
might need to check on endianness. Also, you might try disabling fisu
transmission under idealcondition from userspace as ppc can transmit fisu
after msu.
I had similar issue and got rectified by a header file change.
