Hello,
I have a problem with my brand new iOptron GEM28 mount - when I'm running a photographing session, after some time (around 10-15 minutes) my mount refuses to move in RA. Dec axis works just fine (using either the INDI mount driver or the hand controller), but RA won't work even when I disconnect the mount from the computer - I need to manually reset mount's power. I'm running the following versions of KStars and INDI libraries on my Raspberry Pi 4 running Ubuntu Mate 20.04 LTS (I installed them from the beta PPA):

I'm not sure how would the mount work on the latest stable KStars/INDI, I can't test it because my camera, Altair Hypercam 183M Pro, refuses to work on these versions. I'm also attaching screenshots from PHD2 showing the moment when my mount refused to move in RA (please ignore the bad guiding performance, it was due to my very inaccurate polar alignment - the clear gap between the clouds was very short and I wanted to test Ekos with my new mount quickly). Also, please tell me if I need to attach some other pieces of information (eg. some logs) and how to collect them, if necessary.

Best regards,
Pawel
