Is it possible with the new linux kernel 2.6 to hotplug an ide device
like cdrom/hdd and the kernel to automaticaly recognize it?
I have a IBM thinkpad T40 which has a removable bay for ide devices like
IDE cdrom/hdd/dvd. (and other stuff too like secondary battery a.s.o)
In older kernels like 2.4.x I used hdparm with -U -R options to register
and unregister IDE devices, but it is not working any more on new 2.6.x
kernels.
Also on my desktop I have a hot-pluggable IDE tray/cage where I can
hot-swap HDD, CDROM, DVD, which also is not automaticaly detected.
Where should I search for this feature ?

Hi Greg,
Ok, let's say that we don't talk about my special case with T40.
Let's say that I don't even want hotplug event, but at least a mecanism
to tell to the kernel that it should rescan the IDE devices, or IDE bus
?
But I guess this is a question for another mailing list (like
linux-kernel) not for linux-hotplug.
In the past I've used hdparm -U / -R, but it does not work anymore for
kernel 2.6.x.
Thanks,
Paul

Yeah, the kernel developers need some information on your hardware that
IBM isn't giving out :(
So sorry, I don't think it will work.

I would suggest searching the linux-kernel archives before asking this
question on there again...
Good luck,
