Hi Jeremy > Try removing all FIQ related stuff from your cmdline.txt and just use > the defaults. Works fine for me with 4.1.7-rt8. Well I only ended up disabled FIQ because with it enabled I get the freezes described by Mikhail (and kodi video playback freezes as well). With FIQ disabled I non longer have the freezes, but the skipped frames (that I don't get when rt-preempt is disabled) remain. I will try 4.1.7.rt-8 though.
