--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> --- Note you want to look into the gcc.log file to understand why things are turning into UNRESOLVED. the gcc.sum file is only a summary of what is going on. Also depending on the board you are using or how you are running the testsuite, it could be that the ssh connection has been broken due to the machine crashing. So you really should look into the gcc.log file to understand the exact failure here.
