Bug#735935: grub2: LVM trouble at boot after upgrade to 2.02 beta

[Michal Kašpar]

Hello.
After yesterday's upgrade of grub in unstable, I'm hit by this bug as 
well, so there must be some problem with grub and LVM. Nothing else have 
changed in my up to now running configuration and after downgrading grub 
to 2.00-22, system boots just fine.
The difference is my VG containing root fs doesn't get started at all, I 
have to do lvm vgchange -ay in intramfs shell and after exit, boot 
continues just fine.
In grub.cfg, differences are in using
set root='lvmid/2D6mtT-...
instead of
set root='lvm/vg00-r
and
UUID instead of /dev/mapper... in kernel boot configuration.
