I tested several more times under 2.6.22-rc4, there's no such problem.
The hci_dev_put is indeed a bug, isn't it? it decrement the refcout on more time like you said.
But why the slub doesn't warning under 2.6.22-rc4 but do under 2.6.22-rc3-mm1? I'm puzzled.
And if this is a bug , should I write another post to list? then to mm or mainline? I'm still new to kernel list, thanks you all.
