Will do bisect later. But v5.0 should be okay, could you help double check? Of course. My tests show: v5.0 bad v5.2-rc1 bad v5.2-rc2 bad v5.2-rc3 bad v4.20 good where "bad" means: kernel crashes on boot if sdma firmware is loaded. kernel works ok if we use sdma firmware already in rom. Are you able to reproduce this issue? I started bisecting last week, but ran out of time. I could try again here, if you cannot reliably reproduce it.
