Do you have an alternate means on that machine to connect to the
internet to obtain further updates? Reason for asking is that I use an
Airlink 101 USB-Ethernet adapter (hardwired) and found that it was not
working with
2.6.24-12 - see:
https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/183124

Following the updates (2.6.24-14) & using NM to bring the adaptor back
in, all works again.
