I just upgraded from 11.04 to 11.10 using the update manager tool. The upgrade went smoothly, except for one message about swsusp needing a swap partition to work (I do have a swap partition, and suspend worked fine before and still does in 11.10).
Now on booting up, the machine waits a long time saying it is "waiting up to 60 more seconds for the network configuration", and then that it is "Booting system without full network". At this point, about half the time the system never boots into X (although I can always Ctl+Alt+F1 to log into the terminal). The other half of the time, it goes to the login screen and I can log in, but then the update manager tells me I need to reboot to complete updates (no matter how many times I have rebooted). Both the ethernet and wifi connections work fine.
The only unusual thing I can spot in ps is that I have 8 copies of "nfsd" running.
All I have in /etc/network/interfaces is:
iface lo inet loopback
Can anyone help? thanks!
