I have a 100% reliable way to reproduce this on Ubuntu Karmic x86_64. On any normal system with all defaults, kms and compiz enabled, just login and wait for the screen to blank. That hangs the display right there, and I get these same stacks in dmesg (see my duplicated bug, which actually has two hung stacks, not just the one noted here).
