On a whim I tried updating the CPU firmware from Intel. Didn't really help completely as such (though it did perhaps stabilize it some; I'll do some comparisons with and without).
This time I was running "watch acpi -V" in a shell, and deliberately hitting the machine with some heavy processing (run GreycStoration on a large image). The machine stabilized at about: Battery 1: charged, 99% Thermal 1: ok, 84.0 degrees C Thermal 2: passive , 87.0 degrees C AC Adapter 1: on-line It finally froze, with these values (well within the safe zone). I quickly stuck a desk fan onto the machine and waited a couple of minutes, after which the machine sprang to life again as if nothing had happened, now with temperature in the low 60's. No logs show anything odd; the only event recorded at this point was in syslog: Jul 1 23:00:01 mocha /USR/SBIN/CRON[25369]: (root) CMD (test -x /usr/lib/atsar/atsa1 && /usr/lib/atsar/atsa1) Which I don't know what the point is for (what needs those statistics?) but doesn't seem harmful; and of course preload, which again shouldn't cause freezes like this. -- Hardy kernel causes overheating https://bugs.launchpad.net/bugs/223081 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
