I upgraded with pacman -Syu an odroid-xu4 and an odroid-n2 last night. The following packages were upgraded on the n2.
$this->bbcode_second_pass_code('', '

')
Upon reboot, fstab drives failed to mount. However, once rebooted, mount -a mounted them successfully. This is true for both the xu4 and the n2. This is repeatable. This did not happen before the upgrade.
Here is the dmesg output for the n2 when it finds the drive but does not mount it:

')
Later after the mount -a, dmesg showed
$this->bbcode_second_pass_code('', '
[ 33.404766] EXT4-fs (sda1): mounted filesystem with ordered data mode. Opts: (null)
')
Is this a bug in the newer systemd 242.0-1?
