 Environment:
   > Host Linux with gcc 3.2 and 2.95.3 (tried both). target is an Intel
   > StrongARM SA1110 Assabet Development board. the version of binutils is
   > 2.13.1.
 
 Description:
 
   > You may download the objdump result of two kernel binary at:
 
   > http://www.gnuchina.org/~suzhe/vmlinux-asm.tar.bz2
 
   > gcc 2.95.2 version is OK. But gcc 3.2.1 version cannot boot.
 
   > kernel compiled with gcc 3.2.1 freezed at the first syscall (clone)
   > when execute init kernel thread. I traced into the kernel and found
   > that the syscall (clone) in kernel_thread function has no effect. I
   > knew little about ARM asm language, so I cannot point out which code
   > section is wrong. But I guess we can focus on kernel_thread and

 I'm afraid this is still infsufficient for me to get anywhere.  Without
 knowing precisely what's failing there is nothing I can do, since I
 don't have the development system that you have.  An objdump of the
 binaries isn't going to help much, a linux kernel is just too big to
 contemplate searching for a problem like this by inspection of the
 compiled code.
