Reported by ODM and we also can reproduce on the MP machine that ODM provided [Fix] Intel debugged this issue for half month, finally they provided 4 patches to fix it. Intel tested these 4 patches on many many sof machines, they worked well. [Test Case] Install oem image to Nebula MP machines, there is no hang anymore, and the audio functions all work well. [Regression Risk] Low. Intel already tested these patches on many machines. And we also teste them, the original issue is fixed by them and no new issues found.
