Local fix

Problem summary

  • When ipsec is enabled on a system with ipv6 configured,
    system crashes with stack overflow:
    CPU 0 CSA F00000002FF47600 at time of crash, error code
    for LEDs: 30000000
    pvthread+00E900 STACK:
     060888FC df6_fltr_out_chk+00007C (0000000000000003,..
    

Problem conclusion

  • Some of the RAS traces have been modified to keep stack size
    low so that page fault does not happen, which leads to this
    crash.
