I have been noticing some strange messages since reinstalling the december release a few days ago. Tonight I dug into them and was surprised by what I found.
Even though I had explicitly clicked the buttons to install the firmware for my network cards (Realtek r8169 and Ralink RT3062), I discovered that they had not, indeed, been installed. I corrected this by installing packages firmware-realtek and firmware-ralink.
I also found that what I thought was a standard package, firmware-linux, was also not installed. I don't know whether my system needs it, but I installed it anyway.
I rebooted and most of those strange messages are now gone.
