Well, all I do is call into Bart's new helpers to scan for or

devices ...

The switch to these helpers happened _before_ 2.6.26 and it shouldn't
bring
such behavior change (ditto for new IDE host addition/removal
helpers)...

Please try to git-bisect it when you have some time.

Ok, I will. I worked fine when I last tried your patches. I'll see if I
can track it down too. Been a bit too busy lately as you can imagine.

Do you have something that exercise the same code path you can use ?

I'll see if I can reproduce it with IDE warm-plug support later...

OK, I reproduced it here with IDE warm-plug support
(echo -n "1" > /sys/class/ide_port/ide*/delete_devices)
for devices driven by ide-cd.

It is also reproducible under qemu so I'm scripting it
into git-bisect run now...

I WON!!!

Great, seems that I don't need to learn how ide does ref counting. :)

Thanks a lot!
