Several issues are found. Is this the first time you've tested it? Or did these warnings only show up recently? > ``` > $ grep KMEMLEAK /boot/config-4.18.0-rc4+ > CONFIG_HAVE_DEBUG_KMEMLEAK=y > CONFIG_DEBUG_KMEMLEAK=y > CONFIG_DEBUG_KMEMLEAK_EARLY_LOG_SIZE=10000 > # CONFIG_DEBUG_KMEMLEAK_TEST is not set > # CONFIG_DEBUG_KMEMLEAK_DEFAULT_OFF is not set I'm not seeing any warnings on my machine here, maybe it's something config related. Can you send your full .config ? cheers
