Public bug reported: I have the following stuff in my /etc/rc.local, to disable hyperthreading:
echo 0 >/sys/devices/system/cpu/cpu1/online echo 1 >/sys/devices/system/cpu/cpu2/online echo 0 >/sys/devices/system/cpu/cpu3/online echo 1 >/sys/devices/system/cpu/cpu4/online echo 0 >/sys/devices/system/cpu/cpu5/online echo 1 >/sys/devices/system/cpu/cpu6/online echo 0 >/sys/devices/system/cpu/cpu7/online HT cannot be disabled in my bios, unfortunately. With this stuff in /etc/rc.local, irqbalance tend to crash.
