Yes.

Not completely.
* reboot system after rfkill block bluetooth, sometimes the cfgbit = 0xc0000
I never had cfgbit = 0xc0000 when I power-cycled the system, only when I
rebooted it.
This is why I belive the second point has virtually the same reason as
the first point: bluetooth device initialization fails and thus its
detection by BIOS fails and thus ACPI returns 0xc0000 cfg.
Hence, I belive chances are high that solving the first point does also
solve the second.
While thinking about it... the init problems persisting a reboot could
also mean that not the unblock operation is the real issue but the block
operation - which probably leaves the bluetooth device in kind of a
semi-disabled state or something like that.

Mario
