[lvm-devel] WARNING: dev_open(/dev/mapper/loop2) called while suspended

Hi
With current LVM I'm getting this warning
WARNING: dev_open(/dev/mapper/loop2) called while suspended
(/dev/mapper/loop2 is one of four underlying PV devices)
The vg contains three volumes, a mirror, snapshot and origin.
LV VG Attr LSize Origin Snap% Move Log Copy% Convert
lv1 vg1 mwi-a- 56.00M lv1_mlog 100.00
lv2 vg1 owi-a- 64.00M
lvol0 vg1 swi-a- 16.00M lv2 0.10
The warning happens if the mirror is active, the origin and snapshot is
inactive and the user activates the origin with lvchange -ay vg1/lv2
command. If the mirror is not active, the warning doesn't happen.
2.02.47 doesn't have this bug. 2.02.48 and current cvs does.
In the attachments there are outputs of lvchange -vvvv -ay vg1/lv2 and gdb
backtrace.
So you may still consider trying to fix it before the release...
