Package: initramfs-tools
Version: 0.130
Severity: normal

Hi,

I had noticed this bug for quite a while now, but since I rarely turn my
machine off I left investigating what the problem was until now.

Every time I boot my laptop, it prints a lot of messages like this,
before eventually giving up:

Begin: Waiting for suspend/resume device ...
Begin: Running /scripts/local-block ... done
[...]
Begin: Running /scripts/local-block ... done
Gave up waiting for suspend/resume device.

I traced this down to the swap device being on an LVM partition on my
laptop. The script which automatically determines which device to resume
from stores the blkid in the initramfs, but unfortunately the lvm2
local-block script does not know how to activate LVM partitions based on
blkid. This means the swap device is never created and the initramfs
will never be able to find it.

Is it possible (and a good idea) to store the /dev/mapper path instead
of the blkid when the swap partition is on LVM?

I managed to solve my specific issue by manually setting RESUME to the
correct /dev/mapper path.

Thanks,
James
