Upgrade from 0.7~alpha5.1ubuntu6 to 0.7~beta2ubuntu1 brought this on: on every boot the ”Waiting for network configuration” and ”Waiting up to 60 seconds more for network” messages appear and boot is thus about 2 minutes slower than before. It also says it’s booting without network, but the network is in fact there after I log in.

Downgrading back to 0.7~alpha5.1ubuntu6 makes the wait go away again.

Reproduced this on three different computers on two different networks, both wired and wireless.
