It says there's a 'device_mode' parameter that is trying to be set, but it is invalid.  According to [1], [2], [3], and [4] there's something in /etc/modprobe.d/* that's trying to set it.  It has been fixed in most distros.

You'll need to find what's trying to load alsa with the 'device_mode' parameter and fix it.

hth,
