Sorry for late reply, suffering on a "VPN-Jetlag". 

Here's the promised vmcore.o(last)[1] on pastepin. It's not a "mini"-dump at 
all but a huge 
skirt up to the heals :-) as it has 360M of text and the editor loads about ten 
minutes on 
grandmother's laptop with her 70 years after 36 hours of being online. The 
options are 
with DEBUG=-g and VERBOSE set in the config. 

With the ubt1, a 2070X stack by Asus it's probably the kernel driver I'd have 
to parse into 
the kernel as here at linux a quarrel about it is for years systematically 
delaunching "bills 
driver"; you get the patch as a .zip file on Arch, not as a .deb or .tar.gz or 
whatever and it 
must be compiled by hand; after that you'd to reboot and install the A2DP-fix 
and than you 
can pray (where ever you want to and think it might help you) with the initial 
pulseaudio-
connect at boottime (sometimes it just doesn't recognize the adapter) - so as a 
LiLo-
substitute I prefer EFI-Clover not the GRUB-stuff that doesn't work at all for 
BSD for many, 
many times) and I really don't know how many hours I spent with "sudo 
bluetoothctl" and 
on kernel builts for this 'Ubitek Magic Box'.  

Hope someone can think it over, I know it's old hardware but she'd (the laptop) 
to to spend 
50 mankind-years in bills slavery when I got her finally - probably one of the 
SALVAGED - 
messages at fsck -y in single mode :-)

So take care of it, it's not the way I normally act to sent guys boxing about 
and for the box 
but much more than beeing dead can't happen, can it? - This happened to my cat 
"Rambo" 
who just flew away from me and went straight away under a car - buhuhuhu.... so 
far for 
the revenge thoughts, 

'svn up' is good at this, subversion is much better than git --diff, which 
really doens't work 
at all here. 

Yours, 
Miranda
