Tempo limite do dispositivo Cryptsetup ao montar automaticamente através do Systemd

Por algum motivo, o systemd dá tempo limite em um dos meus dispositivos cryptsetup ao tentar montá-lo. Aqui estão as unidades e o script:

regras do udev:

ACTION=="add", KERNEL=="sd[a-z][0-9]", ATTRS{serial}=="NA8F9WKF",                                                               SYMLINK+="BigHDD", TAG+="systemd"
ACTION=="add", KERNEL=="sd[a-z][0-9]", ATTRS{serial}=="AA00000000065396",                                                       SYMLINK+="clavem", TAG+="systemd"
ACTION=="add", KERNEL=="sd[a-z][0-9]", ATTRS{wwid}=="t10.ATA     WDC WD10EZRZ-00Z5HB0                         WD-WCC4M6HRPV4V", SYMLINK+="HDDsB",  TAG+="systemd"

teste.sh está cheio de testes porque eu estava tentando descobrir por que o tempo limite estava ocorrendo em um serviço único. por algum motivo ao fazer systemctl restart mnt-HDDs.mount, vai bem e monta minha partição... Dá timeout emmnt-mapper-cryptHDDC.device
