Sounds like a memory/cache problem, but may possibly be due to a race condition in the 2940 driver. Ask Justin Gibbs (gibbs@estienne.cs.berkeley.edu) for a pointer to the new driver. Obviously you're having problems building a new kernel - either he or I or someone else may be able to build you one that covers the problem. I would still be more suspicious of your hardware. > Jason T.
