Bugzilla

Eric, I actually was able to emulate this bug's crashes a couple of times in a row. The only recent change to my system is that I freed about 750MB of disk space on my boot partition. The amount of free space on my boot partition is still quite low -- even now it's only a little over 7GB. Which leads me to suspect that my AMD graphics drivers are, like yours, able to use system memory when video memory runs short -- but only if there's a minimum amount of disk space available (since system memory swaps to disk when you overuse it).

All of this leads me to ask: How much free space do you have on your boot partition?

I used a HookCase hook to prevent ioAccelResourceFinalize() from calling its original function. Then I loaded three very busy pages and and scrolled up and down in them continuously. It took 5-10 minutes of this to trigger dtrace script errors and then the crash.
