No proprietary drivers of any kind. Up to the 3.11-rc2 kernel I never had any problems with it. With 3.11-rc4 I've twice so far had the following problem: 0. X has been running for a while with fvwm, a couple of xterms, emacs, firefox, and xclock. 1. Suddenly text scrolling in xterm or emacs becomes extremely slow and grinds to a halt. Moving the mouse (which generates interrupts) resumes the scrolling, but then it stops again unless I keep moving the mouse. 2. At this time there are no kernel messages indicating problems. 3. If I exit X then the console behaves normally. 4. If I try to start X again it paints the background of my desktop and shows the mouse cursor, but nothing else comes up and it's unresponsive to mouse or keyboard input. I have to press C-A-D or the power button at this point. 5. After 1. above occurs, even a warm reboot isn't enough to make X work again. A full power-cycled reboot is needed to bring the machine back to normal. /Mikael -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
