When the UI hangs after applying MPD settings...
ssh and type "systemctl restart rune_SY_wrk"
seems to do wonders, in a few seconds all continues working normally and it saves the new settings, no reboot needed
Also I get a recursive error/segmentation fault that ends with kernel panic when trying to reboot from ssh and have to power it off the hard way.
Are there other logs apart from menu-debug?
[ 78.214183] systemd[1]: mpd.service: main process exited, code=killed, status=11/SEGV
[ 78.229484] systemd[1]: Unit mpd.service entered failed state.
EDIT: the segmentation fault was caused by corruption in the card
