Pity, then the mentioned PR won't be able to help you. I could try to glance over the est attach issue if you'll post full dmesg, 'acpidump -dt', 'sysctl dev.cpu', 'sysctl dev.est' and 'sysctl dev.cpufreq'. Regarding the original problem about increased power consumption: you seem to have desktop CPU with only one SpeedStep frequency, but with TCC cycle throttling. This can be easily verified: you should see only one frequency in dev.est.0.freq_settings, but multiple (8, with stepping of 12.5%) frequencies in dev.cpu.0.freq_levels. Throttling is known not to decrease power consumption and your increase of 1W can be attributes as a measurment error (can't say for sure -- statistics and knowledge on how you had measured the consumption is needed). There is good set of notes from Alexander Motin on the power consumption on 8-CURRENT, http://lists.freebsd.org/pipermail/freebsd-current/2009-May/006436.html perhaps this will give you some further ideas. > The motherboard is a GigaByte P35DS4 And you're running the latest known BIOS, aren't you? > I already used cd1 as device, hence the atapicam device.

Could the AHCI mode be the culprit? Once I had similar messages with AHCI mode turned on some Asus MBs, so I am turning it off regularily. You can also try just enhanced SATA mode set via BIOS -- it could help. -- Eygene _ ___ _.--. # \`.|\..----...-'` `-._.-'_.-'` # Remember that it is hard / ' ` , __.--' # to read the on-line manual )/' _/ \ `-_, / # while single-stepping the kernel. `-'" `"\_ ,_.-;_.-\_ ', fsc/as # _.-'_./ {_.' ; / # -- FreeBSD Developers handbook {_.-``-' {_/ #
