[Panicsel-developers] Segment fault happened when run fruconfig.

[Guo, M. <mi...@in...>]

Hi

	Here I encounter one issue  when run fruconfig on langley.
Can you tell me whether it is a bug of fruconfig?
	
	We can get the fru header, but can not access the corresponding 
board information address.

Thanks
Guo Min

When I check the source , I found the error happens in the following code.
Show_fru()
/* show board fields */
   pfru = &frubuf[(frubuf[3] * 8)]; //here frubuf[3] is 227 '?', and address
fru[1816] can not be acessed.
   lang = pfru[2];
   pfru += 6;  /* skip board header */
