Dear listers,
We currently found that amd frequently cores dump while loading is
high (about 4~5) after we upgrade world & kernel from 7.0-RELEASE to
7.1-PRERELEASE.
I have read -stable and svn log of 7-STABLE, but can not found a
report or a solution. Did anyone have the same issue? Thank you very
much.
