I can confirm same bug on Dimension E521 with nvidia 7300LE after upgrade to jaunty.
This is oddly similar to another bug I had back in 8.04 (I cannot remember the fix but I believe it had to do with nvidia drivers and kernel incompabilities). I have tried the newest drivers (180.51) but still get freezes.
I have reverted to open source drivers (changed "nvidia" to "nv" in xorg.conf) until the bug is fixed.
