That's doesn't sound right, why the problem is not occurring after the first suspend-resume cycle. DSP is in charge of clearing the overflow interrupt and if it is doing it after the first transition to Core OFF, why wouldn't be doing it for the first one. Moreover from the logs sent internally (since it is the same issue and oddly the same resolution), the trace log dump printed is generated in the dsp after clearing the interrupts, so the problem could be the gptimer is configured to autoreload instead of oneshoot or the dsp write is not posted to clear the interrupt (which might be valid issues), but also they could happen after the first transition to OFF. I'm sorry if I didn't ask you for logs but I was seeing this issue internally (and assumed you'll be in the same team of people :)), and given that more information was posted there than here..., but still, if available send the changes you have made.
