There is what I get :

Ok, I'm watching it frame-by-frame. I can see the microcode getting
updated to revision 0x19 as in your working dmesg.

The machine hangs here at the

clocksource: tsc: mask: 0xffffffffffffffff max_cycles: 0x20ac7f6ecc6, max_idle_ns: 440795315461 ns

line too. The exact same numbers even as in the previous run! Strange.

With dis_ucode_ldr there is some more output , with it will stay like this , nothing more.

Ok, can you do redo the first video but with "initcall_debug" on the
kernel command line?

And then do video of another run with "initcall_debug dis_ucode_ldr" on
the kernel command line?

I'd like to see which of the initcalls doesn't return.

There are both videos .. however the output seems kind same this time..

I try to find out more tomorrow but right now I don't even have a clue
where to add some printk's to get some more output :(
