That's right.. the thermal interrupts are being reported, that should have started running cpu's at lower frequencies via some thermald. If that's not handled and the PCU starts enforcing trying to keep the temps under control system starts logging MCE's. Ccing Srinivas who might be able to give a better pointer to check why that's not happening. The log didn't have the exact MCE's reported.. if you have mcelog, please attach that in the report. > > What does your /var/log/mcelog* log file contain? > > -- > Regards/Gruss, > Boris. > > SUSE Linux GmbH, GF: Felix Imendörffer, Jane Smithard, Graham Norton, HRB 21284 (AG Nürnberg) > --
