Hi, Previously I ran CURRENT from some time in April without any problems. Symptoms: Consistently high LA (2.6 to 8.0) with all CPUs idle. At the console, depressing and holding a key does not lead to auto-repeat. At the console, sometimes a key only appears on the terminal after another key is pressed. In xorg, key auto-repeat sorta works, but visibly slower than active xset settings, and jerky as well. Moving mouse around helps. During reboot, when the kernel prints the number of dirty buffers periodically before shutting down, it "freezes" and does not print the next number until I press a key. So it takes multiple presses of "Shift" or "Control" before it actually boots. Nothing suspicious according to vmstat, vmstat -i, pcmstat, top, top -SH, top -m io. What I tried, by myself and because of various advices on IRC: - replacing sc with vt & disabling sc - removing atkbdc from kernel configuration - removing uart from kernel configuration - putting "off" for ttyu0 in /etc/ttys (it had "onifconsole") No luck. Verbose dmesg can be obtained from: http://www.tobez.org/download/dmesg.verbose.2014-07-31.txt Any thought?
