Hi all,

 After I renamed "ibt-19-16-4.*" to "ibt-19-16-0.*" and the kernel failed to
load just once, I rebooted and switched off again and again until today.
However, I've never seen the attempt of the kernel to try to load
"ibt-19-16-0.*"  since that. The kernel came to load "ibt-19-0-4.*' at the
beginning of boot.

 I guess that an internal failure in the AX201 caused my problem. I hypothesize
that trial to load the wrong(broken) Bluetooth firmware caused an invocation of
internal resetting to the AX201. After then, the AX201 became to return the
correct version information to the "btintel" driver, and the kernel
successfully loads the correct bt firmware, "ibt-19-0-4.*'.

 Whether my hypothesis is true or not, my problem appeared to solve. I will
mark this thread as resolved.    

 Many thanks all,

Takahide Nojima
