I posted a while back about getting a thermal trip whenever I take the machine off ac. Zone 3 jumps from ~30C to 150C in 5-10 seconds. I received no responses except me-too-style ones. I just started looking again and noticed that this only happens when the machine boots with ac plugged in, _then_ you move to battery. If you boot on battery there is no trip. Also, Linux (Suse 10.0) works fine. No thermal trip. In fact on suse I see other thermal zones with signicantly lower temps (e.g. tz0 is typically <40C while freebsd amd64 current as of today is >50C). And this is with freebsd running on the console (i.e. no X server) while suse is running X. The only significant difference I can think of is that freebsd is running the ndis emulator for the broadcom wireless part which appears to have some overhead--but removing it from the system doesn't seem to change the temp. The last issue is that like some other folks the system will lockup if I let powerd bring the clock down when idle. Lockups are easily reproducable but don't appear to be related to any particular state (e.g. I saw a lockup in the lowest frequency and also at one above lowest--though perhaps it was really switching to the lowest frequency and locked up before the printf made it to the console). Any suggestions on how to diagnose any of these problems would be appreciated. I'm most concerned about running too hot and locking up the system. Without resolving these things it's kinda hard to run freebsd. Sam
