Comment 8 for bug 1573982

Faced with the same behavior yesterday, the only workaround for me became adding line "vgchange -ay" to /usr/share/initramfs-tools/scripts/local-top/lvm2.

Didn't change any config for a couple of months before this issue, only executed apt-get upgrade on regular basis.

However, now I get the following warnings during boot:
