** Description changed: After upgrading my Dell Latitude E6400, computer was running very slowly. After few search, with powertop, I found that three modules was consuming lot of CPU: - snd_hda_codec_idt - snd_hda_codec_generic - snd_hda_intel (like https://askubuntu.com/questions/91359/100-0-usage-by-audio-codec-hwc0d0-realtek) After adding them in /etc/modprobe.d/blacklist-snd.conf, my computer works again like a charm, with cost of missing sound.
