I am having a similar but slightly different problem. When the new firmware first became available, I also was getting the message that there wasnt enough space. But then a few days later, the message went away. Since then I have tried to update the firmware a couple of times, but it does not work. It tries to update for 20 minutes or so (web interface unresponsive during this time), but then after about 20-30 minutes, the web-interface becomes responsive, but the update apparently didnt work, because it still says I need to update. Any one experience this or know the cause/solution might be?
