Dear Lazyweb

After todays or yesterdays daily package update (Sid) several kernel modules, namely thinkpad_acpi, snd-hda-intel and probably others are not loaded automatically anymore. So my Thinkpad T500 had no support for audio and several power management functions anymore. Once I found out that the missing kernel modules where the problem, the fix was easy: just add the corresponding module names to /etc/modules to enforce loading of the modules. But I wonder what caused the sudden change? Why are the modules not loaded automatically anymore? I usually update my Sid packages every morning so some package update from yesterday or today might have caused this. Looking at the packages which where updated, I found nothing suspicious. Has anyone an idea at which package I should look?

Update: Looks like the problem was related to the recent update of base-files to version 6.2 which introduced the new /run directory in combination with udev. Downgrading base-files to version 6.1 (via snapshot.debian.org) fixed the problem.
