Hi I have installed FreeBSD 6.1-RELEASE on my Compaq Presario 2656AU laptop, but it occasionally hangs. I traced the problem to powerd so I made a script that kept changing the clock rate by setting the sysctl dev.cpu.0.freq. This script normally makes the computer hang within 10 seconds or so. I then added a few printf's here and there which have let me to believe that the problem is somewhere in sys/dev/acpica/acpi_throttle.c, acpi_thr_set It only prints the first letter of a printf just after the line THR_SET_REG(sc->cpu_p_cnt, p_cnt); The problem happens with and without cpufreq.ko loaded. The kernel is GENERIC. Any Ideas? Cheers, Tim
