n900 goes offline (and stays offline)
 

Since a few weeks, my n900 has developed the habit of dropping its 2G connection and not reconnecting. The phone itself is online (I get calls and SMS), but the data connection is down.

It's properly configured to search and connect (minimum interval of 5 minutes), but it doesn't do this and needs manual connect.

I'm running CSSU-testing 7.2 and KP-52, only the latter was recently upgraded, but I can't find anybody else complaining about this in the KP thread.

Also have 3G/2G/Dual Mode selection applet and Advanced Interface Switcher.

I have 3G and wifi off, so only 2G. Never seen this before and it now happens every day.
