Issues after recent updates to F16

Sun Jun 17 01:24:20 UTC 2012

Recently I updated F16 on my laptop.  Since then I have encountered the 
following issues:

1) I see the following error message being repeated constantly in 
/var/log/messages

Jun 16 17:35:17 peglaptop dbus-daemon[1147]: ** (upowerd:1807): WARNING 
**: Property get or set does not have an interface string as first arg

Jun 16 17:36:47 peglaptop dbus-daemon[1147]: ** (upowerd:1807): WARNING 
**: Property get or set does not have an interface string as first arg

This message occurs in bunches every 30 seconds to 1 minute.

2) I started noticing the display flickering.  What's interesting is 
that the display flickers when I boot the laptop up on Windows 7 as 
well.  So it could be that it's a hardware problem, but I just replaced 
the motherboard due to other video issues.

3) The battery monitor applet keeps disappearing/re-appearing on the 
bottom panel.

Has anyone else seen similar issues?
