ntfs: (device loop1): parse_options(): Option utf8 is no longer supported, using option nls=utf8. Please use option nls=utf8 in the future and make sure utf8 is compiled either as a module or into the kernel. ntfs: volume version 3.1. BUG: MAX_LOCKDEP_CHAINS too low! turning off the locking correctness validator.
