Comment 21 for bug 479296

I think I might be getting this bug as well.
After upgrading to Karmic I get random freezes.

Most often everything but the mouse pointer freezes. Not even caps lock works.
Pressing the power button on the computer does not initialize a shutdown as it usually does.

When I get the problem I could see the screen flashing black once very rapidly.
I have not found any useful info in my syslogs...

I'm on the 185 NVidia driver.
