Btw., I'm also puzzled by only seeing a ucode update message
here for CPU1 - I just went through the logic again and can't see
why this would not also be done for CPU0. Could you make the
pr_debug() in microcode_intel.c actually print something, so we
can see whether at least collect_cpu_info() would get called
for it, hopefully allowing to deduce what happens subsequently?
