Public bug reported:

I believe I am seeing GPU lockups when running Unity 3D on Oneiric with
the Nouveau driver using a GeForce 6150SE nForce 430.  I'm not entirely
sure what causes them, but I can usually make them occur by repeatedly
minimizing and maximizing windows, showing/hiding the Unity panel, etc.
This behavior seems to be new in Oneiric (I was able to run Unity 3D
without any major issues under Natty.)

This is my video card:
00:0d.0 VGA compatible controller: nVidia Corporation C61 [GeForce 6150SE nForce 430] (rev a2)

Xorg logs show:
[ 87595.983] [mi] EQ overflowing. The server is probably stuck in an infinite loop.
