My Slackware 13.37 started to freeze from time to time. Mouse and keyboard stops working, while xmms still playing the song. I paste my syslog and I hope someone could see the reason it crashes.

This question came from our site for professional and enthusiast programmers.

i915 is your Graphics driver, try downgrading or upgrading it for several versions. If that doesn't resolve the issue try again with the latest version and file a bug with that version.
