#597994 gnome-panel: "system monitor" does not show disk I/O when using LVM?

I use the gnome-panel "system monitor" widget, showing bar charts of
CPU/disk/network/etc activity.

Generally all of these seem to work -- but on my home computer, the
"disk I/O" chart always shows zero activity, even when there's
clearly lots of disk I/O going on.  However, on my work computer, the
disk-I/O chart seems to work correctly.

The only obvious difference between these two systems that may be
relevant is that my home system has most of its filesystems in LVM
(so the "df" command shows "/dev/mapper/..." for the disk devices).

I'm wondering if the gnome-panel system-monitor has a bug where it
fails to work with LVM...

Thanks,

This bug has a few possible fixes in upstream bug
https://bugzilla.gnome.org/show_bug.cgi?id=160441

Unfortunately patch in https://bugzilla.gnome.org/show_bug.cgi?id=160441#c21
does not directly apply to squeeze version at least. But the concept
should work anyway.

from bug report comment

works on squeeze. Now my encrypted laptop disk stats are nicely visible.
Please consider applying to unstable and stable too.

For stable this will most certainly not happen.

Ok. How about backports then?
