+description = """The flash snapshot restore does not function correctly. Basically when you use “if=pflash,format=raw,unit=0,file=OVMF_VAR.fd", it crashes when trying to restore a snapshot.
+
+The root cause is:
+
+1. In system/runstate.c, function vm_state_notify loops through vm_change_state_head list and calls the callback function for each entry.
+2. One of the callback function pointer points to function postload_update_cb in hw/block/pflash_cfi01.c.
+3. In function postload_update_cb, it calls qemu_del_vm_change_state_handler in which the entry element memory is freed.
+4. Note that, it is still running in the loop, the entry will be visited and get executed, the function pointer may point to a wide memory."""
