hello,

Is there a new status?

I doubt I miss something else, so I met this issue.

Base on this patch, in futher, if we plan to use IPC as wakeup source, so this patch should be in our main branch, this issue will be a real issue.

So what I want is fix this issue base on this patch, not just revert it.
