I also have an M10 tablet with OTA10.1 with an non functioning location
service and intermitent GPS icon. As per BQ's request I'm attaching some
(fragments of) logs.
1) "# ubuntu-location-serviced-cli --bus system --test" outputs text
like this:
length=27 context=0x3b9968

and exits with a segmentation fault at a random moment in time.

Hope this info is of any use.
