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.
