--- Comment #3 from Peter Bergner <bergner at tenstorrent dot com> ---
Given the closeness of the release and the size of the performance degradat=
ion,
should revert the problematic commit and reapply it after the release with =
some
additional fix for the 470.lbm degradation or do you think we can get that
additional fix in before the release?
