+Subject: [PATCH] symbol: fix -S cannot work with kaslr detection
+
+When kernel enabled the CONFIG_RANDOMIZE_BASE, crash needs to add "kaslr=auto"
+in crash command line to tell crash to decode the random address.
+But when with "-S" in command line, crash would bypass the kaslr option
+that cause symbol from kernel image is mismatch with ram on a live system.
+
+The fix is provided by Tao Liu <ltao@redhat.com> from crash-utility upstream,
+and not merged to crash master yet.
+
+Upstream-Status: Pending
