floating point operation of ppc

[lily]

hi,all:
    i build an embedded linux on powerpc 405ep,i need execute floating point operation,and i enable "math emulate" option in kernel, i run a while(1)loop ,in the loop there was floating point expression ,after test ,i found the while (1) exit because of the floating point computation,that is the floating point can't execute on ppc stablely.Is there someone meets the same problems ,please give me some suggestion,thanks!!!

                                                                                                     lily
