udev/power_supply battery oscilates between remove and add

Hi. I hope I'm addressing the appropriate mailinglist regarding this. If 
not, please direct me to the right place where I should write.

I'm using Debian Wheezy/Testing, kernel 3.2.15-1 on a HP PowerBook 4515s 
laptop.

I noticed that /var/log/syslog is getting spammed with messages like in 
the attached syslog-laptop-mode_spam.log.gz file.

Also, at the same time, "upower --monitor" shows the messages from 
upower-monitor.log.gz.

In Windows XP I don't see any issue with the battery and also running HP 
Battery Check 
(http://h20239.www2.hp.com/techcenter/battery/battery_ts.htm) I got the 
result that the battery is functioning correctly, but is week 
(admittedly it is more than a year old, but still holds a charge for 30 
mins).

So it looks like a kernel issue. I started checking the udev events with 
'udevadm monitor --property' and got the messages from the 
udevadm_monitor.log.gz file.

This happens only when the battery and the power cable are connected. 
When running with the battery removed or without the power cable 
connected (running only on battery) this is not happening.

Here are some more discussions about this:
- a Debian Bug reported: 
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=638970
- and also a thread on the Upower mailinglist:
