--- Comment #161 from Don Lewis <truckman@FreeBSD.org> ---
(In reply to Nils Beyer from comment #153)
I suspect that there is a pattern sensitivity issue in the icache since I've
seen quite a few reports of this.  Nothing that we do in software should af=
fect
this.  The same is true of any microcode fixes from AMD.  As long as the er=
rors
aren't too frequent (a hard stuck bit would cause very frequent errors) and
they are always correctable, then this shouldn't be an issue.

If you happen to be in communication with AMD, you might want to tell them =
how
frequently you see these.
