The situation has improved slightly, although attempting to run two VirtualBox guests at the same time inevitably leads to a lock-up. I've just taken to running one at a time. Not ideal, but until more debugging can be done, it's the only option I have. I ran into this using nvidia and radeon both. I can't really find a pattern, but I do see it when Windows is trying to draw a new window, or dim the screen when UAC kicks in... BTW, anyone know how to get a good dump when running Xorg? I'm not sure I've ever been able to, even when I panic on something non related to X or video drivers. -Brandon _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
