Long shutdown

[pollanza]

I've been using this wonderfull release in my home pc and netbook from the release date and I found it really really good!
There is only one problem that is affecting LMDE in my eeepc 900, from about a week it takes a lot to shutdown. After I press the shutdown button in the panel and the confirmation, it loads for about a minute, then the gdm appears and then finally it shut down...
Is there a way to solve this? A few days back all worked normally and I haven't done nothing strange, only update regularly!
Thanks in advance!
