I'm trying to chase down the lock-ups I've been seeing with the 3.11
kernels on the quad cpu board. It's not very helpful every third time I
rebuild a kernel module, the board locks-up...... Anyway, trying to
eliminate heat as one reason. I want someone to run this on a quad with
the "stock" 3.0.35 kernel. Please don't use 3.11. I've got that covered.
This will heat up the cpu. That's the point. I'm hoping that it doesn't
result in a lock-up, but if it does, that's good. That means that it
isn't 3.11 kernel specific, just the result of heat. *If you have your
quad board in the WB plastic case, remove the lid so the heatsink is
exposed.* (There is no need to point fans at it, just remove the case
lid. The thermal trip/throttling works. 85 deg C, ISTR.)
Code:
--------------------
sudo csos-cleanInstall-testing cpuburn
cpuburn-a9 &
watch -n1 cat /sys/devices/virtual/thermal/thermal_zone0/temp
--------------------
Note the starting CPU temp. (Probably in the early 40's.) After ~10mins,
you'll probably be seeing temps in the mid 70's. Note it down. If you
haven't had a lock-up after an hour of testing, you are not going to see
one. Ctrl-C the watch task updating the cpu temp to the screen every
second, "fg" the cpuburn-a9 and Ctrl-C that too. Job done. Thank you.
NB. For anyone interested. The cpuburn package is built from "stock"
cpuburn-1.4a.tar.gz source plus ssvb-cpuburn-a9.S (cpuburn-a9) from 'Is
your ARM Cortex-A9 hot enough?'
(http://ssvb.github.io/2012/04/10/cpuburn-arm-cortex-a9.html).
(cpuburn-a9 does generate more heat than burnCortexA9 and there is no
need to run multiple instances, so that's why we are using it.)
