I have a problem whit my N900. It's a great device, but now I'm stuck on a strang problem.

When I was playing around and looking for some nice stuff on my phone, I got an error "userspace full". So I started a terminal. I found out that the /home (/dev/mmcblk0p2) was almost full (99% of 2G)

So i remove almost all apps (including python) and I saved 100Mb.
Back in the terminal, du helped me discovering that I only had 100Mb in /home/opt and 8Mb in the hidden directories in /home/user.
Actualy, du discovers only 108Mb. Then I have 80Mb free space. That all on a partition/disk of 2Gb, That's 1.8Gb lost?

Does someone reconise the problem? And does someone know a solution?

Thanks, Bjokke.
