A little query which does not really matter,
but which leaves me slightly puzzled.
I'm running linux-2.6.6-rc2 under Fedora-1
on my Sony C1VFK Picturebook.
This has in-built Bluetooth.
To start this running, I say "spicctrl -l1"
(when the blue Bluetooth light on my laptop comes on)
followed by "service bluetooth restart".
All this works perfectly.
But if I give the command "spicctrl -l0"
to stop the inbuilt Bluetooth
I am never able to restart it,
except by re-booting.
I couldn't see from a very brief (and ignorant) look at the source
why the sonypi_ioctl() call couldn't be reversed.
Perhaps there is some command I could give
to restart Bluetooth, short of re-booting?
[IIRC, I could start and stop Bluetooth like this
in older kernels.]

Hi Michal,
> Have you done some research in hcitool cc cc dc bug?
I thought it was clear why this fails. If not, post it again with
"hcidump -x" to show what happens, but in a seperate thread. It is not
nice to ask off-topic questions in a complete independent thread.
Regards
Marcel

Thanks for the advice.
I compiled linux-2.6.6 with
# CONFIG_BT_HCIUSB_SCO is not set
and now I can start and stop Bluetooth (with spicctrl) as often as I wish.

you can keep every Bluetooth daemon running even if no device is
attached. They will re-init themself if you power-up your internal
Bluetooth device. What I think that happens is that the stopping with
spicctrl is the same as a physical unplug and this causes a kernel oops.
Check if you have CONFIG_BT_HCIUSB_SCO enabled, if yes, disable for now
or apply the attached patch.
