Comment 2 for bug 134466

Well it seems this might be a duplicate of this bug:
https://bugs.launchpad.net/ubuntu/+source/linux-restricted-modules-2.6.15/+bug/48395

Similar symptons are being reported there (in particular the wifi related dmesg output) and it could be this bug is being caused by location as suggested by some comments there (different wireless access points causing firmware bugs to show up) i.e. I'm in a different wireless hotspot at the moment than I was yesterday, so it may not be apt update related.
