However there are code in a number of places that will then only accept cpu 0 and 1 as cpus to handle. When I changed to code to be the same as for ARM64 things worked as expected: static intarm_get_smp_cpus(void){ return MAX(get_cpus_online(), get_highest_cpu_online()+1);} Jan Jan KarlssonSenior Software EngineerSystem Assurance Sony Mobile CommunicationsTel: +46 703 062 174<a href="mailto:Firstname.Lastname@sonymobile.com" target="_blank">jan.karlsson@sonymobile.com</a> <a href="http://sonymobile.com/" target="_blank">sonymobile.com</a> <img border="0" width="84" height="15" src="cid:image001.gif@01CFE865.529F8280" alt="Sony logotype_23px height_Email_144dpi"> </div></div> -- Crash-utility mailing list <a href="mailto:Crash-utility@redhat.com">Crash-utility@redhat.com</a> <a href="https://www.redhat.com/mailman/listinfo/crash-utility" target="_blank">https://www.redhat.com/mailman/listinfo/crash-utility</a> </blockquote></div> </div>
