Hello, I have a similar problem here with cx88_alsa:
HAL was not starting, one of the things to fix it was to add module cx88_alsa to /etc/modprobe.d/blacklist After that I issued 'modprobe -v cx88_alsa' manually and got the following traceback: (I issued the command twice; the second time modprobe hanged and was killed with <CTRL>-C) uname -a Linux zeus 2.6.24-15-generic #1 SMP Fri Apr 4 03:10:59 UTC 2008 x86_64 GNU/Linux Apr 6 19:54:50 zeus --
