SUMMARY: level 15 interrupt

Hello, all,
I haven't received any response yet, but I have found the problem. The
ss4 is at ok prompt by itself from working status, so I suspect that it
maybe one of the memory chips go to bad. After take it out one by one
and put it back, one of them is bad. When put bad one back, it reboot
repeatly, give some page errors.
It also give:
NOTICE: ZS3:ring buffer overflow.

What is ZS3 and ring buffer?

Thanks.
