Hi all,

Recently, vmstast show crazy big "bi" value even though the system has
no stress. Is this known issue?

Thanks.

underflow?  also looks like -3 or -ESRCH.

Adding Jens in case he has any idea about it.

First question, what does 'recently' mean? In other words, in what
kernel did you first notice this behaviour?

Thans, Randy, Jens.
I dagged awhile and I've found this is -mm specific and known issue.
It was fixed by Hannes. (ref Message-ID: [ref])
