On a system with a GeForce 6150SE integrated GPU, the system becomes mostly unresponsive shortly after logging in. It does not lock up completely, but seems to only process pointer events or keystrokes once every few seconds, and pings from another machine on the network start returning in 3-5 seconds instead of a few ms.
This began in raring and happens on every subsequent release (and also under precise, if a HWE stack from raring or later is installed); under quantal it does not happen.
Based on the hardware, symptoms, kernel versions, and NvMSI=0 workaround, these upstream bugs might (or might not) be related:

WORKAROUND: Use kernel boot parameter:
nouveau.config=NvMSI=0
WORKAROUND: Use proprietary nvidia-304 driver.
