After installing freebsd 5.2 the errors there was no more errors at boot-time but acpi was still not working. so first of all i ask google about acpi and freebsd and the first things which was noticeable to me was a message which does not appear at my boot output, like this: (1) acpi_cpu: throttling enabled, 8 steps (100% to 12.5%) furthermore or better said therefore my system is mission sysctl-variables like (2) hw.acpi.cpu.performance oder hw.acpi.cpu.economy i googled again but could not find a reason for this behavior and it seems to me a little bit strangely because i know to 100% that cpu throttling is supported by my cpu and it is working fine under windows (i know windows does't take it so exactly with acpi standard so it isn't realy a good comparison). after the google session i posted the problem in a german freebsd-forum (bsdforen.de) but nobody could help me. so i decided to update the system to 5.2-current to get the lastest source and to see if acpi is working with it. when the update finished i rebooted and after login the cpu-cooler got slowed down in his speed but after a few seconds it came back to full speed. first i examined the output of dmesg and again the lines like (1) does not appear and therefore there was no sysctl-variable like (2). so i thought i could download a knoppix-with-acpi-version and look if acpi is working there. i did it and realy the cpu-cooler got slowed down and came only up to full speed when i was doing some cpu intensive operations. i dumped the /proc/acpi/dsdt content to a file and rebooted the system. next i did a iasl -dc and copied it to /boot. then i modified the loader.conf to this: acpi_dsdt_load="YES" acpi_dsdt_name="acpi_dsdt.aml" after this i rebooted the system and i got the message that the acpi table was overwritten by the OS. but it brought no success. i looked at the freebsd-handbook and found out that it could fix some problems by define the variable acpi_osname and i tried it out by setting acpi_osname="Microsoft Windows NT" because this string was in the decoded dsdt-file. so now i don't know what i could do anymore and i post it to this mailinglist. are there any possibilities i did not thought about? sorry for the long post and i hope my english is good enough so you understand the problem. yours sincerely cu -- NEU : GMX Internet.FreeDSL Ab sofort DSL-Tarif ohne Grundgebühr: http://www.gmx.net/dsl
