[Bug binutils/5492] New: unable to boot linux kernel 2.6.23.9 on R2D+ SH

Subject: [Bug binutils/5492] New: unable to boot linux kernel 2.6.23.9 on R2D+ SH7751 board using binutils 2.18 based SH-Linux toolchain
Date: 17 Dec 2007 12:03:04 -0000

Hi,
I have successfully built SH-Linux toolchain using the following sources:-
Binutils: 2.18
Glibc: 2.7
GCC: 4.2.2
Kernel Headers: 2.6.23.1

I could successfully compile Linux kernel 2.6.23.9 using the above toolchain 
and but upon execution on R2D+ SH7751 board, it was observed that the kernel 
was unsuccessful in booting the board. Every time I pressed "b" to boot the 
board, it would reboot. This can be illustrated as follows:-

----------------------------------------------------------------------------
RTS7751R2D[root]# lilo
Added linux *
RTS7751R2D[root]# reboot
The system is going down NOW !!
Sending SIGTERM to all processes.
Sending SIGKILL to all processes.
Please stand by while rebooting the system.

OBSERVATIONS:-
1. There is no issue while building and booting linux kernel 2.6.22.1 on    
   R2D+ SH7751 using the same toolchain.
2. The above behavior is observed with highlander SH7780 MP Board as well.
3. It has been observed that the board boots successfully when compiled  
   with the toolchain built using Binutils version 2.17.50 but keeping rest 
   of the other sources same as mentioned above.


   Is there any compatibility issue between Linux Kernel 2.6.23 and Binutils   
   2.18?
