--- Comment #5 from Nathan Whitehorn <nwhitehorn at FreeBSD.org> ---
That's not true. These "errors" cause resets, which hose IO performance, as
well as polluting system logs. Ignoring them significantly improves IO on
affected systems (factors of two). There should be a sysctl or something to do
this.
