Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.8 kernel[0] (Not a kernel in the daily directory) and install both the linux-image and linux-image-extra .deb packages.
If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.

I upgraded kubuntu 12.10 to 13.04 last night, and observed the update- initramfs bug (https://bugs.launchpad.net/ubuntu/+source/kmod/+bug/1073062). Upon restart, KDE loads, but NetworkManager takes 100% cpu, and fails to allow wireless connections. (Changing the backend from NetworkManager to Wicd does not help.) However, if you restart and select the 3.5 kernel instead of 3.7 kernel, the problem disappears completely. I'm happy to help debug and provide further information if you can tell me what it is that's needed.
