Bug Description
Many people have reported the "random X freeze" with "put your card here". I have been hunting down this bug in forums and making some durability tests in my pc.
Ok the problem is very random.... yes it is very random, sometimes 5 min. after boot sometimes it can take up to 3 or 4 days to trigger, however I have hunted down the flash player to trigger the bug quicker than anything else, down to a couple of minutes of hd video playing in flash might trigger the bug, so I am suspecting some video memory leak (not ram but vram) somewhere in the X server or the driver, bug happens with and without compiz enabled.
Most of times just the X server freezes however the mouse still moves, also corruption is visible and many flickers on screen and the mouse might freeze after. Some times the hangup is complete no SSH, sometimes machine is accessible via SSH, and rarely switching to console is posssible, however returning to the X server freezes completely the machine.

I rolled back to the 173 driver and the machine has been rock solid for 4 days of uptime using flash, flash hd video, hd video under mplayer vlc totem etc., games and even tried svn versions of XBMC. and no problems so far.
I can also confirm this bug with a zogis card 7300gt 256mb. running an AMD64 X2 (32bit Jaunty & stock 32 bit kernel) on a Biostar GeForce 6100 AM2 Mobo. I just updated my family's machine and got the same results with the 180 driver, rolling back to the 173 driver solved the freezes but alas no VDPau.
I forgot the first system (The intel) is also running 32 bits versions of Ubuntu Jaunty and stock Jaunty kernel.
