When I switch to sched_ULE, these anomalies occur: * the net/boinc_curses window comes up very slowly, updates are quite sluggish * the science programs (setiathome, einstein, simap) loose track of the hartbeat from time to time, resulting in restarting processes. According to top, restarted science processes run with either (NICE=i31, PRI=171) or (NICE=19,PRI=8). * the load avarages in top fluctuate around 4 instead of 2 (there are 2 concurrent science processes on an otherwise almost-idle dualcore laptop). The boinc client is started using the boinc rc.d script, so it runs at idprio 31. Laptop: Asus A6JE, dualcore Intel T5600 FreeBSD 8.0-CURRENT #34: Sat Nov 3 18:30:36 CET 2007 root@195-241-214-37.dsl.ip.tiscali.nl:/usr/obj/usr/src/sys/RENE i386 powerd is enabled using the default configuration, the laptop mostly runs on AC power. I've attached the output from 'sysctl kern.sched' and 'cpuid' and my kernel configuration. Any ideas?
