This shows memory corruption. The function argument here is "y yet or" in little-endian, which is a substring of the displayed message:
#5 0x00007fd339527465 in display_message (plugin=0x8e7320, message=0x9369d0 "The disk drive for UUID=c8f4e850-9317-4950-82f2-a79cffcedf1c is not ready yet or not present") at ./plugin.c:466

So it's some kind of buffer overflow.
