Freezes after a while. fthrottle_mode=1, vblank_mode=0: CPU usage is very low. After a few minutes, both monitors suddenly go blank (switch off), keyboard is dead, I have to push the reset button. Nothing in log files. fthrottle_mode=1, vblank_mode=3: 0% CPU usage. Again, freezes. fthrottle_mode=2, vblank_mode=0: System seems to run stable (testing for at least 25 minutes now). But this is strange: CPU usage is at medium level (around 55-70%) at normal size. When I resize the glxgears window so that it becomes smaller, CPU usage *increases* to around 80-90%. Now I increase the window so that it is bigger than the standard size. CPU usage goes down to 10-25%. I have no clue why, this makes no sense to me. When I increase the window once more, CPU usage will slightly go up again. A nearly full-size window will consume about 50% cpu resources. However, the smaller the glxgears window, the more responsive the other applications become; a bigger glxgears window makes everything else become a bit slower. fthrottle_mode=2, vblank_mode=3: 0% CPU usage. Freezes. So far, fthrottle_mode=2, vblank_mode=0 seems to be the best option. I'm not quite sure this is 100% stable though, but until now it works. If it freezes, I'll report this of course. I agree this is not a problem with the CPU usage, but it seems to be somehow related to it. Generating high CPU usage without OpenGL applications still freezes the system. Maybe, now at least we can narrow the problem to a specific module? I actually don't expect it to be Mesa but I have no knowledge of these things...

Yes, but to be on the safe side, I've tried it again. It didn't help though. These options are on when using BusType PCI and don't have any bad influence there. > PS: Why do you set NoMTRR? For no particular reason. I've just searched for solutions on various forums and tried out all the options I could find. I have turned it off now, but it doesn't make any difference either. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. ------------------------------------------------------------------------- Using Tomcat but need to do more?
