I've had this issue for a few months and have not been able to fix or find out what the cause is. When I play a video in full screen (usually Flash within Chrome browser, but occasionally with VLC), after about 1 minute, the audio will skip/freeze, video will also skip and go black or show an odd pattern, and the entire system becomes unresponsive. I can't switch to a different TTY or Sysreq REISUB. Journalctl -b -1 (from the last boot) does not show anything unusual. Here's an example video that causes the full screen crash: http://vimeo.com/15247292 (NSFW). I'm running KDE with xf86-video-ati driver on a Radeon HD 5770.
Help me debug this issue. What could it be? How do I find out what the problem is and/or how to avoid it?

are you using vdpau by any chance? That's only thing I can think of that could cause issues with both flashplayer and vlc. Although pepper-flash from chrome don't support vaapi like the flashplayerplugin if I'm not mistaken.
You could try if downgrading xf86-video drivers or kernel to linux-lts to see if that solves your issue.

I may have found what's causing the issue. I'm using Redshift, which messes with the color temperature. So far, disabling Redshift before going full screen, I haven't had any more crashes. I'll try this for a while longer, and probably make a bug report if it keeps on working.
Update: Turns out the crash would happen even without Redshift or xgamma. I've changed the Radeon DPM setting to "performance" instead of "balanced" setting, and I haven't had a crash in a day.
