patch -p1 worked for me to apply it.

actually, i dont think i need to hold lock over copyout. attached is
my version of the patch (untested)
thank

oh, didn't patch it with the -p1 option, maybe this is why. I rebuild the k=

and it does work. When using the built-in-adapter you not just have to rebo=
ot but to turn it off for at least 10 secs., and then reboot into freeBSD a=
gain. Here's what I'm having right now:
/etc/rc.d/bluetooth start ubt0

root@freeBSD13:/usr/home/miranda # /etc/rc.d/bluetooth start ubt0

=C2=A0So, you got to tell it at least twice because of dmesg often calling:=
ng_hci_process_command_timeout: ubt0hci - unable to complete HCI command OG=
F=3D0x3, OCF=3D0x3. Timeout
The ubt0 is the Asus stack, I can't setup the internal ubt1 anymore at all.=
Maybe I'm gonna patch with the -p1 flag tomorrow.=C2=A0
@warner Is there a way to patch a running kernel and just reboot or is it a=
lways in a new buildkernel environment? I did "patch=C2=A0 =C2=A0bt.diff";=
=C2=A0
@maksim; special way to patch correctly?
