Yes, it improved things greatly. I first ran with just powerd for several hours and that worked fine. The next day I was able to use powerd and cx_lowest=C2 for the better part of a day (including watching a few flash videos). By the end of the day intr started to run away again, so not out of the woods yet, but at least this shows we're going in the right direction. Also, while poking around in the BIOS settings I noticed in one of the "information only" screens that I don't usually visit one line about the "minimum cpu speed" is 1.00 GHz, which the sysctl output above seems to verify. So where the throttling code was getting all those other numbers I don't know. Meanwhile I've actually not been running FreeBSD for most of this week I've been working on re-partitioning my new disk and running ubuntu. So 2 interesting pieces of information there, first the "CPU Frequency Scaling Monitor" for the gnome that comes with ubuntu never goes below 1 GHz, so that bit seems extra verified. Second, I can watch all the flash videos I want while doing other stuff in the background (like restoring the backups of my data) without any problems, so add that to windows in terms of OS' that work on this same hardware. Now that I have finally figured out how to boot windows, linux, and 2 FreeBSDs on the same disk I'll be able to set up 7-stable i386 and 9-current amd64 to see how they compare to the 9-current i386 I was using previously; so I should have more information in a few days. hth, Doug -- Improve the effectiveness of your Internet presence with a domain name makeover! http://SupersetSolutions.com/ Computers are useless.
