I am moving a high definition frame into a pci frame buffer. This process takes somewhere around 100 ms on my Dual Xeon system, however on the two AMD systems I have tried it is taking about 1 sec (1000 ms). The two systems I have tried are a single processor athlon system and a dual processor athlon system. (Both use the AMD chipset .. the single uses the AMD760 and the dual uses the AMD760MP). Both boxes are running kernel 2.4.6. Any suggestions? Thanks, Jason
