Does it trigger when you just boot up and the immediately shut down
w/o doing any work on it ?

Could you try whether the following triggers the bug as well: Boot up,
do work or whatever. Make sure your data is sycned to disk. :)

# echo 0 >/sys/devices/system/cpu/cpu1/online

If that does not trigger, then check whether it survives the
shutdown/reboot. If it does we look further.

Can you provide the list of modules loaded ?
