What linux distro are you using? Have you tried importing other modules? like sys ?

I have the same problem. Not sure what happened, but it was probably the update. I also noticed that DHCP gave a different IP address to the Raspberry Pi. It used to be 192.168.1.136 with Raspbian, and ArchLinux before the update (both rebooted multiple times and maintaining this IP). Anyone has any...
