Does it also happen, if your system is idle? What is your current CONFIG_HZ_* setting? Try the lowest rate for your system. Also you could try to disable CONFIG_NO_HZ (if set) in your kernel config. > I've yet to try it, but I've read that adding > "clock=pit noapic nolapic" to the boot parameters should fix it. As a i486DX does not support any APIC hardware this parameter will not help. BTW: If your system time drifts away due to bad crystals you should run an ntpd for a few days. It will use adjtimex to trim your system's settings to get less time drift. jbe -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
