--- Comment #1 from Steffen Nurpmeso (steffen@sdaoden.eu) ---
Hello.  I am now on 4.19.107 and "it happened again".
Semantic was slightly different, i realized the notebook is not going to sleep,
and found un-KILLable bluetoothd and rfkill instances, i even had to shutdown
the computer hard.  The following listing can be better understood with a
snippet from my /root/zzz.sh that is invoked if acpid emits LID (close) events:

while :; do
   down_off
   lid_exists || break
   sleep 1
   lid_is_open && break
done

Here is the /var/log/kernel snippet:

P.S.: that zzz.sh has also

   command -v rfkill >/dev/null 2>&1 &&
      act '( rfkill block all ) </dev/null & sleep 2'

which should be the "rfkill".

I know the r8822be module (the only one, i cannot link it in) is in staging on
4.19.  (It seems to have been integrated in 5.4, yet i have had not time to
update to that one.)  It works just fine, how ever large it is, but i want to
remark that Wifi can get down to ISDN speed and less if i hear music via
bluetooth.  Not always, but in such situations, if i stop listening to music
via bluetooth, Wifi speed goes up to 3.6 Mbit per second (the maximum here)
immediately.

And one more addition, because whereas r8822be for Wifi is in staging in 4.19,
the bluetooth one is not, i think.  (No idea of kernel, actually.)  And the
rfkill(1) did only act on bluetooth here, since Wifi was gone before:

Hello.
It happened again, but the trace is the same. I am updating to kernel series
5.4 now, so i close this, ok?  I post nonetheless because here the second RIP
comes without the leading [cut here], which made me wonder a bit.
