[ltp] Ultrabay & crash after suspend-to-ram (with solution)

[Nils]

Hi there,

if somebody encounters the problem of a blinking cursor after resuming from 
suspend-to-ram it can be this error:

You can reproduce it with the following steps:
- insert a dvd ultrabay device
- insert a cd or dvd
- mount the device
- => 1st suspend-to-ram
 (... sleep ...)
- => 1st wake up
- umount the device
- echo 1 > /sys/class/scsi_device/1:0:0:0/device/delete
- echo eject > /sys/devices/platform/bay.0/eject
- remove the ultrabay device 
- => 2st suspend-to-ram
 (... sleep ...)
- => 2nd wake up
- system is crashed with a blinking cursor in the left corner

*****
I found the following solution: After removing the device I do 
everytime an echo "0 0 0" > /sys/class/scsi_host/host1/scan
and then it works fine.
You can also add the command e.g. in /etc/acpi/sleep.sh and then it's startet 
automatically before every suspend-to-ram action. It doesn't matter if it's 
needed or not.
