Subject: Re: Re[6]: 3.4-rc smpboot: do_boot_cpu failed(-1) to wakeup CPU#1

I'm a little bit confused about this thread, because I'm facing a similiar
problem on my system:

I have a CentOS 7.7 AltArch i386 installation:
Linux erbusze 3.10.0-1062.18.1.el7.centos.plus.i686 #1 SMP Wed Mar 18
12:57:13 UTC 2020 i686 i686 i386 GNU/Linux

on this CPU:
smpboot: CPU0: Intel(R) Core(TM) i7-6700 CPU @ 3.40GHz (fam: 06, model: 5e,
stepping: 03)

with these boot errors:
[    0.160538] Kernel panic - not syncing: Fatal exception
[   10.166450] smpboot: do_boot_cpu failed(-1) to wakeup CPU#1

I tried several different values of cpu_init_udelay in the kernel command
boot line, but with no changes to the described behaviour.
