This is also a SER L1 " SER catches error: 0x1000".

Even it does recovery very fast. I expect you still can see the log
if connection happened.

I'd summarize the cases you met:

1. SER L1
   It is just a notification from firmware to driver, so we'd ignore this.

2. "firmware failed to ack for leaving ps mode"
   Please try to disable power save parameters mentioned by previous mail.

3. disconnection
   I think this is major problem you want to fix. If so, bisect kernel
   to address this.

   By the way, the first log you shared shows that disconnection happened
   after SER L1 about 50 seconds. SER L1 seems not a related event.
   More, the disconnection might depend on AP you are connecting, so 
   keep the experiments in the same environments if possible.
