Trace error: "dma eI2" when doing pause/release

[keqiaozhang]

This issue happens on BYT when playback or capture. but it doesn't affect audio. The reproducibility is low < 5%.
rmbox-t.log
rmbox.log

How to reproduce:

1. aplay -Dhw:0,0 -f dat -c 2 /dev/zero & arecord -D hw:0,0 -f dat -c 2 /dev/null -i
2. press the space key to do pause/release for capture.
3. check the rmbox

@xiulipan lets also dump the error code if we can. It's probably harmless notification and could be verbose trace level.

@lgirdwood
will done. I believe this is because BYT will have three channel enable with only one IRQ handler.
Let me try to enable all SSP on BYT and have a test.

@ZhendanYang could you check if this issue is still there with new logger?

[ZhendanYang]

@mengdonglin BYT is in bad health at the moment. I can't check this issue for now. I'll check this issue as soon as BYT become healthy.

[lgirdwood]

@ZhendanYang I cant find "el2" in the source. Can you re-test with master.

[ZhendanYang]

Blocked by #443 . And rmbox and logger are both empty.

@ZhendanYang Any update?

@tlauda
I think we can close this issue. Since no more rmbox is working now.
