--- Comment #24 from cheako+kernel_org@mikemestnik.net ---
My testing shows that cold/worm boot is a red herring, the issue is random and
if you do it one way enough times you may well find you can get *both* states.

@Mario what were you thinking for DD?  For me this happens while going
multiuser, so I really would like kernel cmdline or `/etc`/`initramfs` setting
and not echoing things on a prompt.

I added this to `~/.config/autostart/xmessage.desktop`
```desktop
[Desktop Entry]
Type=Application
Exec=sh -c 'sudo dmesg|grep hci0|xmessage -file -'
Hidden=false
X-GNOME-Autostart-enabled=true
Name[en_US]=xmessage
Name=xmessage
Comment[en_US]=xmessage preformance monitoring
Comment=xmessage preformance monitoring
```

I get either no hci0 logs, xmsg is empty, or this:
```dmsg

I had been using BT for a few months, so suddenly loosing it after a kernel
upgrade really sucks!
