I have started a small site intended as a knowledge base for problems related to nforce2 + linux + lockups. If you experience lockups under Linux that seems to be related to heavy io, please check out the URL below. NVIDIA has remained pretty tacent about all this, but there is a support request with AMD. I'm interested in setups that work or do not work. Refer to the site on how to submit a report if you wish to do so. People with boards not yet listed are encouraged to submit a report.
