NVIDIA NVRM Driver Freeze Error

If your system hangs (sometimes for minutes) when watching video, or random lockups, or display corruption, or unusually high system load, then you have an NVIDIA driver and multi-core CPU problem...

NVRM: os_raise_smp_barrier(), invalid context!

You are most likely using 10.10 with the default "latest" driver - which is actually now 6 months old and suffers from a few nasty bugs...

To fix this, upgrade to the latest driver by adding the following repository:

sudo apt-add-repository ppa:ubuntu-x-swat/x-updates
sudo apt-get update
sudo apt-get upgrade

You will now have (as of 25 March 2011) have version 270.29...

Now reboot and kiss goodbye to problems... but do have a very smooth running system :-)
