hello ,
Compiled and booted 5.10.3-rc1+.

dmesg -l err gives...
--------------x-------------x------------------->
   43.190922] Bluetooth: hci0: don't support firmware

My Bluetooth is Off.

Is this a new warning?  Does it show up on 5.10.2?

thanks for testing?

this does not show up in 5.10.2-rc1+

Odd.  Can you run 'git bisect' to find the offending
commit?

Does this same error message show up in Linus's git tree?

quoted

i will try to do "git bisect" .  i saw this error in linus's 
tree.

The bug is in -stable, too, so it is probably easiest to do
bisect
on
-stable tree. IIRC there's less then few hundred commits, so it
should
be feasible to do bisection by hand if you are not familiar
with
git
bisect.

My wild guess would be commit b260e4a68853 ("Bluetooth: Fix slab-
out-
of-bounds
read in hci_le_direct_adv_report_evt()"), but I don't see what
might
be wrong
with it unless some BT device sends a bad report which used to be
accepted
but is now silently ignored.

hello,

Did  "git bisect" in  a typically ok fashion and found that 5.9.0
is
working for bluetooth related. But 5.10.0-rc1  related is not
working.

some related information in bisect.txt  attached.

That's really odd, as that commit only has a Makefile change.

i will try to work on it again

Also, why run this as root?

there may be some problem in my sudo configurtion or the way in run
sudo.\
when i run "make modules_install" and "make install" using sudo typical
files 
ownership changes to root.

That's fine when installing the kernel, but not when building or running
git, please don't do that.
