Hi, Martin
Thanks for your reply and so detailed info :)
Looks like there is a very big chance that the rcu issue in your case
was caused by the driver of some device producer...
But still, rcu should have some check or warning while it was used in
wrong way, or may be this is really hard to detected?
Will keep try to follow it.
