This message is not UEFI specific, but generic filesystem code generates it. So you could 1) At fs_probe_unsupported() in fs/fs.c, change log_err() to log_warning() [or log_info()] 2) Set CONFIG_DEFAULT_LOG_LEVEL to 3(error) [or 4(warning)] to suppress the message. Or you may simply want to modify _log() so as to add a preamble, like "WARN:", in front of the message. -Takahiro Akashi
