[ltp] R51 & SuSE ACPI Ultrabay

[FeRD]

It's generally suggested that a:

/sbin/hotplug stop

is a good thing to do before suspending the machine, that may cut 
activity to the CD-ROM device enough to do what you want. (Although it's 
not a sure thing, I doubt your machine is really considering the CD-ROM 
a "hotpluggable" device. It may be the best you can reasonably do, tho.)

Because the UltraBay isn't under hotplug control, there really isn't a 
module to unload -- the module controlling the CD-ROM is just the 
standard IDE interface, and you probably don't want to unload that! 
<G>   ...You'll have to resort to ACPI (/proc/acpi/ibm/bay to be 
specific) to cut power to the UltraBay without killing off the IDE 
interface to important things like your hard drive.

See a recent message to this list why games with /proc/acpi/ibm/bay 
don't always work the way they should anyway. (Hell, I've never gotten 
my CD-ROM drive to properly hot-swap even under Windows 2000!)
