-- The scripts was already attached after step 2.
-- The error message was triggered at the first time.
-- system can resume from S3 and playback can work. but 'pcm_write' error will occur, I will attach the log.

A new bug(#637) was created to following the 'pcm_write' error.

Summary:
The ipc error(
error: ipc error for 0x60000000 size 0xc) also exists after the first time resume, but this is only a print issue, the functionality is OK, we can lower the priority.Test env:

@mengdonglin looks like a duplicate, can we mark and close ?
mengdonglin commentedon Dec 25, 2018
@lgirdwood thesofproject/linux#370 is more complicate than this.
May we keep it open until The ipc error(error: ipc error for 0x60000000 size 0xc) is fixed on APL?
libinyang commentedon Jan 5, 2019
As this issue doesn't block any function test cases, I suggest we set it as P3 and put it in low priority. What's your opinion? @mengdonglin @markyang

@markyang can you check this again with latest kernel/FW. There have been some fixes in this area. Thanks.
markyang commentedon Jan 14, 2019
@lgirdwood Audio can be resumed, but the ipc error(ipc error for 0x60000000 size 0xc) still exists with the latest build on APL with PCM512x.

@markyang This is a FW crash that's not being detected by the driver. I've added a kernel issue
