Tiejun, I'm a little confused by these patches, because the actual critical exception handlers are still commented out: /* Critical Input Interrupt */ START_EXCEPTION(critical_input); CRIT_EXCEPTION_PROLOG(0x100, BOOKE_INTERRUPT_CRITICAL, PROLOG_ADDITION_NONE) // EXCEPTION_COMMON(0x100, PACA_EXCRIT, INTS_DISABLE) // bl special_reg_save_crit // CHECK_NAPPING(); // addi r3,r1,STACK_FRAME_OVERHEAD // bl .critical_exception // b ret_from_crit_except b . Are you working on fixing this? I'm trying to fix it, too, but I think you're way ahead of me. -- Timur Tabi Linux kernel developer at Freescale _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
