I have just played a youtube video (coincidentally the youtube message from AMD's John Byrne regarding Catalyst!) and I have just checked that the following messages show up in the dmesg log:
[ 2053.298531] radeon 0000:05:00.0: Packet0 not allowed! [ 2058.548486] radeon 0000:05:00.0: Packet0 not allowed! [ 2166.793537] radeon 0000:05:00.0: Packet0 not allowed!
Given that the video is very short and I haven't played any other youtube video the system hasn't crashed (yet). I presume that if I were to play other videos the system would hang.
I saw that also at at least one time. I'll look in my logs for this when it hangs.
