Bug#758808: systemd: timed out waiting for lvm devices

[Vladimir K]

I have this problem too, not every boot, but some 1 in 2-3 boots. Home partition times out.
Just plain ext4 on LVM, no encryption.

>From the log:

 systemd[1]: Job dev-mapper-mf4sys\x2dhome.device/start timed out.
 systemd[1]: Timed out waiting for device dev-mapper-mf4sys\x2dhome.device.
 systemd[1]: Dependency failed for /home.
 systemd[1]: Dependency failed for Local File Systems.
 systemd[1]: Dependency failed for File System Check on /dev/mapper/mf4sys-home.
