Subject: [2.6.18.2] ide_core bug: kobject_add failed for ide ...
Hello,
ide_core is loaded (while putting in an USB stick) as module the first
time after reboot - all works fine. The USB stick got mounted and a ls
is done to show the files on the root of the filesystem of the stick.
Afterwards, the stick is securely removed from the system.
Afterwards, ide_core is unloaded with rmmod (after usb-storage has been
unloaded) - ok.
Next step is to load ide_core again. Now, the following error can be
found in /var/log/messages:

The module is loaded and seams to work fine afterwards.
