Reqestor, please provide the complete dmesg or /var/log/messages
which includes the moment of connect, not only disconnect.

I suspect this may be a dup of bug 153971. Fill dmesg should clear it.

Hi, kernel from  ftp://people.redhat.com/zaitcev/153971/ solved the problem.

Thanks for the messages. Indeed, there was a double kobject registration.
I think this can be marked duplicate.
