I was running Gentoo before, and everything was running smoothly. I was able to, for example, playing music while compiling, or using firefox. Right now, when I try to play music while compiling, I've got lag. It clicks, and I'm unable to listen to music normally. When Firefox loads a page, it clicks too. Simple operations like changing of virtual desktops give the same result. I first suspected the scheduler. I used 4BSD, tried to switch tu ULE2. It was worst. I then tried CORE, same thing. I then checked DMA : # sysctl -a | grep dma [snip] hw.ata.atapi_dma: 1 hw.ata.ata_dma: 1 # atacontrol mode ad0 current mode = UDMA100 Seems to run normally. As I'm fairly new to the BSD world, I don't know what to check or suspect. I've spotted weird CPU usage by xorg, or by software supposed to be lightweight (xfterminal for example, while compiling and scrolling the window gave me heavy load). Standard xorg port, and modular xorg gave me the same result (I'm currently running under modular). I suspect that my configuration (MergedFB on ATI Radeon 9200) could be a problem. Is there anything to check to look for the right cause of this problem ? You can find my kernel config file, my xorg.conf, an output of dmesg, and lspci right there : http://www.calaquendi.org/freebsd/ Thanks, -- Julien Cassignol.
