Re: hibernate does not power down

[Kernel Guardian <kernelgardian@xxxxxxxxx>]

hmmm with bluetooth device equipped I assume. :)

Already discuss about suspending on laptops in this mail list. I use
this script for suspending laptops.
It is tested against F16 on asus laptops.
========== /etc/pm/sleep.d/custom-ehci-hcd =====================

VERSION=1.1.1a
DEV_LIST=/tmp/usb-dev-list
DRIVERS_DIR=/sys/bus/pci/drivers

unbindDev() {
 echo -n > $DEV_LIST 2>/dev/null
 for driver in $DRIVERS; do
   DDIR=$DRIVERS_DIR/${driver}_hcd
   for dev in `ls $DDIR 2>/dev/null | egrep "^$HEX+:$HEX+:$HEX"`; do
     echo -n "$dev" > $DDIR/unbind
     echo "$driver $dev" >> $DEV_LIST
   done
 done
}

bindDev() {
 if [ -s $DEV_LIST ]; then
   while read driver dev; do
     DDIR=$DRIVERS_DIR/${driver}_hcd
     while [ $((MAX_BIND_ATTEMPTS)) -gt 0 ]; do
         echo -n "$dev" > $DDIR/bind
         if [ ! -L "$DDIR/$dev" ]; then
           sleep $BIND_WAIT
         else
           break
         fi
         MAX_BIND_ATTEMPTS=$((MAX_BIND_ATTEMPTS-1))
     done
   done < $DEV_LIST
 fi
 rm $DEV_LIST 2>/dev/null
}

case "$1" in
 hibernate|suspend) unbindDev;;
 resume|thaw)       bindDev;;
esac
