Am I correct?
This is probably a memory caching problem - most Intel chipsets (particularly of the P100 era - except the HX chipset) don't cache above 64MB. > How do I make sure the RAM disk is created in the upper 64 Mb? There is a patch for the 2.1.x kernels to use the higher memory as a very fast swap partition. It probably isn't in the main kernel yet though.
