Ubuntu Troubleshoot

Ive found two error on my ubuntu box (Linux tarantula 2.6.17-11-generic #2 SMP i686 GNU/Linux), the first problems is in my alsa driver, found dmesg output full of this kind of strings;

hda_codec: invalid dep_range_val 0:7fff
hda_codec: invalid dep_range_val 0:7fff
hda_codec: invalid dep_range_val 0:7fff
hda_codec: invalid dep_range_val 0:7fff

to fix it just add this strings to this file /etc/modprobe.d/sound

options snd-hda-intel probe_mask=3 position_fix=3

The second error that pop out on dmesg is my ndiswraper wont work perfectly, so i try this link http://ndiswrapper.sourceforge.net/mediawiki/index.php/Uninstall
