I did a debug build. Found it loops forever in this loop in
topology-x86.c:404.
/* Get package/core/thread information from cpuid 0x0b
* (Intel x2APIC)
*/
if (cpuid_type == intel && has_x2apic(features)) {
unsigned level, apic_nextshift, apic_number, apic_type, apic_id = 0,
apic_shift = 0, id;
for (level = 0; ; level++) {
ecx = level;
eax = 0x0b;
hwloc_x86_cpuid(&eax, &ebx, &ecx, &edx);
if (!eax && !ebx)
break;
}
