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.
