It's not a deterministic problem, it just happens 'eventually', but nearly 100% of the time it does happen -- when I start X or play with the framebuffer directly (mmap(2) of /dev/tty or /dev/mem with the offset of the video card). Has anyone else run into this problem? I haven't tried with the latest -CURRENT, but every kernel from January through August that I've built of -CURRENT has exhibited this problem. I have an ATI Radeon 9600 mac edition, in a MDD w/ 1.25GB RAM. - Justin
