same problem here. I ran an upgrade using the nokia package manager (don't know which packages were updated), and before finishing all packages I see a reboot happening, and on the white Nokia screen I see a message that it's upgrading something (prob. flashing). Then, after a while the icons on the desktop stopped responding, which happens also some time after rebooting the phone.

Now, I have removed all widgets from my desktop, and the unresponsive icons problem is gone, but the phone still runs through its battery much faster than before, even though no process in 'top' shows large % of CPU use..

I have had no time yet to check which packages got updated. what I did see is that dpkg.log is empty.

Any hints on what to check for in syslog?
