But the attached program is very easy to compile and start. I tried to extract only what's necessary from the involved code. There are no hidden trojans inside, i promise. My kernel is 2.2.17 with ext3 patches from Steven and the tnt drivers from NVIDIA. I hope this patches do not affect the tests but if you have any suggestions i will remove what's necessary to make the tests more believable. On 2.4.0-testX i will do the tests at home in the evening.
