I just hung a machine here while attempting to kexec. It appears to have onlined all of the secondary threads, and then hung here: kexec: Waking offline cpu 1. kvm: enabling virtualization on CPU1 kexec: Waking offline cpu 2. kvm: enabling virtualization on CPU2 kexec: Waking offline cpu 3. kvm: enabling virtualization on CPU3 kexec: Waking offline cpu 5. kvm: enabling virtualization on CPU5 [...] kvm: enabling virtualization on CPU63 kexec: waiting for cpu 1 (physical 1) to enter OPAL kexec: waiting for cpu 2 (physical 2) to enter OPAL kexec: waiting for cpu 3 (physical 3) to enter OPAL I'm running benh's next branch as of thismorning, and SMT was off.
