I noticed that the updated and freshly-installed systems were using different kernels. The upgraded system had linux-386 and the freshly installed one linux-generic. When I installed linux-generic on the upgraded system, it worked fine again. It therefore seems to me that actually update-manager failed to install the correct kernel.
Whatever the case may be, as requested, I am attaching the results of the 3 commands for both the broken and the running system. ** Attachment added: "dmesg-broken.txt" http://launchpadlibrarian.net/20479839/dmesg-broken.txt ** Changed in: linux (Ubuntu) Status: Incomplete => New -- Update breaks sound, network, booting.
