 |
|
I have a Dell Inspiron 600m notebook that I use at work. I have a second battery, which is hot-pluggable with the ide dvd/cdrw, in a modular bay on the side of the machine.
I thought that 2.6 was going to support IDE hotplugging, which theoretically should allow me to swap the battery out and insert the dvd/cdrw drive without having to reboot to recognize it.
However, I can't seem to figure out what I need to do to make this work. When I swap the battery for the dvd/cdrw and then try to mount a disc, I get

I'm currently running 2.6.1-rc1 with udev and hotplug. My kernel config is here.
2.6.1 has a kernel option, CONFIG_BLK_DEV_IDEPNP, which I thought might be key to this whole thing. But even with this option enabled, my dvd/cdrw is not recognized unless it's present at boot time.
After unpacking the sources for 2.6.3, I notice that the CONFIG_BLK_DEV_IDEPNP has mysteriously disappeared (and I see no references to this in the change logs). Anyone know what this might mean?
Does anyone know if what I'm trying to accomplish is practically possible? Am I missing something in my kernel or udev config? Is there a patch I need? It works in Winblows, so surely it should work in gentoo!
Thanks for any suggestions... |
