You probably did not run it at 1200 for 2 hours and then flashed a new kernel, rebooted, and tried another build directly. This might have caused certain parts to heat up already to an extent where it needs a bit of rest before running again. I expect it to work after a cold boot, though. While we're at it (questions for you, and my answers to them) (a) what cpufreq governor are you using? [performance] (b) do you have battery plugged in? [no] (c) where is gcc and source located? [btrfs on USB HDD] The problem here could also be related to the USB hard disk which is powered by the AC100, or the btrfs filesystem going crazy from time to time. > Marc, could you please change this to 1000mV in git? Running at > 1200mV really seems to upset stability. Marc, as it helps Gordan, I support this. I'll do testing on a cold boot later today or tomorrow (that is, either soon or in about 19 hours). -- Julian Andres Klode - Debian Developer, Ubuntu Member See http://wiki.debian.org/JulianAndresKlode and http://jak-linux.org/.
