This works on my machine (Sager 4750V) so far, and gives wonderful information: hw.acpi.cpu.px_control: -1 hw.acpi.cpu.px_highest: 0 hw.acpi.cpu.px_lowest: 2 hw.acpi.cpu.px_current: 1 hw.acpi.cpu.px_supported: 2200 1800 800 hw.acpi.cpu.px_usage: 4.62% 25.70% 69.66% (running `make clean' in /usr/ports just to push it a little) This is great! Thanks so much for posting this! This completely makes sense now that I would see the CPU speed reported as ~801MHz when the machine would boot up. I can't thank you enough. What are the chances that this could be imported into current? I am running... # uname -a FreeBSD gambit.gargantuan.com 6.0-CURRENT FreeBSD 6.0-CURRENT #0: Mon Jan 10 18:33:07 EST 2005 mwoliver@gambit.gargantuan.com:/usr/obj/usr/src/sys/GAMBIT amd64 > Unfortunately if you run this laptop under heavy CPU load, CPU will=20 > heat up pretty fast and 'acpi_ec' will adjust delay to prevent=20 > excessive heat.

I do see some ACPI errors on my laptop when I boot it up, such as: (dmesg -a | grep -i acpi): acpi_cmbat0: battery initialization start acpi_acad0: acline initialization start acpi_tz0: _CRT value is absurd, ignored (154.8C) acpi_acad0: On Line acpi_acad0: acline initialization done, tried 1 times acpi_ec0: info: new max delay is 70 us acpi_ec0: info: new max delay is 100 us acpi_cmbat0: battery initialization failed, giving up <-- ugh! acpi_ec0: info: new max delay is 130 us acpi_ec0: info: new max delay is 170 us acpi_tz0: _CRT value is absurd, ignored (154.8C) acpi_tz0: _CRT value is absurd, ignored (154.8C) acpi_ec0: info: new max delay is 900 us acpi_ec0: info: new max delay is 11000 us acpi_tz0: _CRT value is absurd, ignored (154.8C) acpi_tz0: _CRT value is absurd, ignored (154.8C) acpidump stuff is here: http://michael.gargantuan.com/sager_4750v/acpidump.asl http://michael.gargantuan.com/sager_4750v/dsdt.out http://michael.gargantuan.com/sager_4750v/sysctl_hw.acpi > Laptop is not for number crunching after all. ;-) ooops! ;) --=20 Mike Oliver [see complete headers for contact information] --ikeVEW9yuYc//A+q Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (FreeBSD) iD8DBQFB+UdxsWv7q8X6o8kRAvfFAJ9tljqGbXALfrM8n2ehKOQ34y20LwCfUDJ0 57YQ3eM50tbmS8PklRL85pA= =+nS0 -----END PGP SIGNATURE----- --ikeVEW9yuYc//A+q--
