I merged your patch into our images. I have not seen a single failure since
then.

At the same time, we tried to reproduce the problem Rajat had reported
originally. Unfortunately we have not been able to reproduce it. I don't know
if that is bad luck, if we did something wrong (most likely), or if something
else changed in the infrastructure since Rajat did his tests.

Either case, I would appreciate if this patch could find its way upstream.
I don't feel comfortable to enable AER without it. Feel free to add

Tested-by: Guenter Roeck <groeck@xxxxxxxxxxx>

Thanks,
Guenter
