I have the same problem, actually almost...
It was working for about 2 weeks then it stopped doing so and has shown after reboot Interrupt count: 0 as well as wrong Video info which was not corresponding to the HDMI source.
A firmware upgrade didn't help.
After trial and error, with rebooting, reset to factory values several times and downgrading firmware it started to work again. Last thing I did was a downgrade to 20170412 and while I was going to do an upgrade it started to work again after I flashed the lib of the 20170608.
Now, it stopped to work again
As to my previous trial and error, it doesn't seem to be a hardware fault. The video info shows 1766P60 while the HDMI source is set up as 720P25. Even after rebooting. I tried different sources and HDMI cables as well.
Anything else I can try @admin ? This time it worked for a week only
