I have a soekris 4801, which iirc has the same CPU, with the same TSC bug: the tsc clock slows down under some situations : iirc when kernel scheduler runs the idle task The kernel has detected this for ages, and switches to another clocksource, 1st pit, then finally to scx200_hrt, which has higher resolution, and less overhead accessing it. root@voyage:~# dmesg | grep -i -E 'tsc|clocksource' [ 0.000000] Fast TSC calibration using PIT [ 0.401200] Switching to clocksource pit [ 6.431014] Switching to clocksource tsc [ 8.423737] Clocksource tsc unstable (delta = -103967911 ns) [ 8.433916] Switching to clocksource pit [ 47.369942] Switching to clocksource scx200_hrt root@voyage:~# more /sys/bus/clocksource/devices/clocksource0/*clocksource :::::::::::::: /sys/bus/clocksource/devices/clocksource0/available_clocksource :::::::::::::: scx200_hrt :::::::::::::: /sys/bus/clocksource/devices/clocksource0/current_clocksource :::::::::::::: scx200_hrt IIRC, available-clocksource used to have all the clocksources tried, that has evidently changed somewhere along the line. root@voyage:~# uname -a Linux voyage 3.4.4-voyage #1 SMP PREEMPT Sun Aug 12 12:01:41 HKT 2012 i586 GNU/Linux So youre hanging ? and not spontaneously rebooting ? there was a problem with 0.8.0 or 0.8.5 relating to contents of /etc/modprobe.d/4801.conf, a missing "options".
