Thread: 2012 MacBook Air (5,2) runs too hot, even with fans at full speed


hello,

have 2012 macbook air (5,2) running ubuntu 12.04 installed natively. have installed latest applesmc kernel module mactel-support ppa, , run macfanctld.

under normal user operations (web browsing, email, etc) system runs fine , cpu core temps normal (50 - 60 degrees c).

if run compile uses both cores lasts more few minutes, cpu temperature gets dangerously hot - 90's c, , i've seen reach 100 c. cancel compile @ point because unsafe temperature running at.

during time fans correctly crank maximum speed (6200 rpm), problem isn't fans aren't working correctly.

since long-running compiles of embedded linux distros take hours @ time complete, i'd run daemon throttles cpu speed once temps reach threshold (e.g, 90 c).

unfortunately cpufreqd not work , segfaults upon starting. issue described here:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=644567

have rebuilt ubuntu precise cpufreqd debian package suggested patch, segfaults reason when starting.

can give me advice on can keep cpu getting hot? i'm running out of ideas.

thanks,

scott

ivy bridge cpu's temperature threshold 105 celsius before start throttle automatically.
ivy bridge traditionally runs lot hotter sandy bridge.

Thread: Can not create raid array: mdadm: no raid-devices specified.

hello! i'm trying setup software raid on server, fail @ first step: code: root@sandnabba:/root# mdadm -c /dev/md0 -c512 -l5 /dev/sdc1 /dev/sdd1 /dev/sde1 mdadm: no raid-devices specified. what doing wrong!? are sure -c equivalent --create? also, think need space after -c , -l options, value shouldn't command, or should have = between. @ man pages mdadm , double check spelling.

Thread: HOW TO: Package and theme GTK+ / Gtkmm apps in Linux for Windows

hi, if developing platform independent software in linux using gtk+/gtkmm , you've managed cross compile windows, guide you. i'm posting because after researching topic myself, encountered many posts people have abandoned gtk+/gtkmm wxwidgets because of gtks ugly default appearance in windows/wine. gtk+ themeable in windows/wine gnome. have set correctly . . . here's how. guide gtkmm gtk+ similar. (1) firstly, download , install gtkmm windows using wine. (you have if have cross compiled app windows) https://live.gnome.org/gtkmm/mswindows (2) run these commands create proper directory structure. (substitute 'proj' whatever project called) mkdir ~/proj mkdir ~/proj/bin mkdir ~/proj/etc mkdir ~/proj/etc/gtk-2.0 mkdir ~/proj/lib mkdir ~/proj/lib/gtk-2.0 mkdir ~/proj/lib/gtk-2.0/2.10.0 mkdir ~/proj/lib/gtk-2.0/2.10.0/engines mkdir ~/proj/share mkdir ~/proj/share/themes (3) move directory gtkmm installed (probably ~/.wine/drive
