[ltp] T23, ibm-acpi and UltraBay hotswapping

[David Tansey]

here are my docking/undocking scripts (and events/ files) -- got them
somewhere online and only modified them slightly.

dock.sh:
  #!/bin/bash

  status=`/usr/bin/awk '/^status:/ { print $2 }' /proc/acpi/ibm/dock`

  echo dock > /proc/acpi/ibm/dock

  # if ide1 (cdrom) is already there exit
  if [ -L /proc/ide/hdc ]; then
        exit 1
  fi
  # else register it
  sleep 1
  /bin/sync
  hotswap -c 1 rescan-ide

chvt 1
sleep 1
chvt 7

undock.sh:
  #!/bin/bash

  status=`/usr/bin/awk '/^status:/ { print $2 }' /proc/acpi/ibm/dock`

  if [ "$status" == "docked" ]; then
        ifdown eth0
        /bin/sync

        # make sure the bay's cdrom is unmounted
        umount /cdrom

        #idectl not working properly on Debian sarge at the moment.
        #/usr/local/sbin/idectl 1 off
        #so use hotswap:

        #unregister ide1
        hotswap -c 1 unregister-ide

        if [ -L /proc/ide/hdc ]; then
                exit 1
        fi
        echo undock > /proc/acpi/ibm/dock
  fi

chvt 1
sleep 1
chvt 7

events/dock:
event=(ibm/dock GDCK 00000000 00000003|ibm/hotkey HKEY 00000080
00001008)
action=/etc/acpi/dock.sh

events/undock:
event=(ibm/dock GDCK 00000003 00000001|ibm/hotkey HKEY 00000080
00001008)
action=/etc/acpi/undock.sh

hope that helps. i switched to hotswap because i was getting a lot of
failed suspends/resumes after undocking. it has helped. i still
sometimes get failed resumes, but very infrequently.
