Thanks for your suggestion. I've taken sometime to review that patch you suggested. 
It solves part of the problem. And it can set ratelimit on a single device, which
is good. 

But this patch solves the problem in a different way. 

1. Some users are very nervous to notice this kind of error logs. This patch can
give them an option to disable these logs entirely on the whole system level 
instead of just set a ratelimit on a specific device.

2. The sysctl configuration can be persisted after a system reboot. Users may dislike
these AER logs appearing again after a system reboot.
