 on two machines now (one with wireless installed, one without), i can
 quickly lock them up with:


 {{{
 # init 3
 # echo 9 > /proc/sys/kernel/printk
 # while :
 > do
 > sleep 1
 > echo mem > /sys/power/state
 > done

 }}}


 the resulting log (from the non-wireless case, since it's cleaner), looks
 like:
