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 affect
this.  The same is true of any microcode fixes from AMD.  As long as the errors
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.
