Hi, David, Segher,
Maybe it was caused by floating exception.I found that,system received
a program check exception,the reason for it was REASON_ILLEGAL.
I also use show_regs to print the NIP in exception,it seemed that
,this exception was caused by 'vmhaddshs' instruction in user mode of
init process .
Is vmhaddshs avaliable on e500mc? My cross compile tool is gcc-4.1.2-glibc-2.5.0
