+Subject: [PATCH] Fix for 'sys' to properly display the PANIC message
+
+Using 'sys' command, we can view the panic message with general system
+information. If we run RISCV64-based vmcore, PANIC message is not properly
+displayed.
+
+The reason is that the string "Unable to handle kernel" is not
+completely matched with the panic_msg[]. The corresponding kernel commit
+is 21733cb518471.
+
+Without the patch:
+  crash> sys
+        KERNEL: vmlinux  [TAINTED]
+      DUMPFILE: vmcore
+          CPUS: 4

+         PANIC: ""
+
