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. Thanks! -- Regards/Gruss, Boris.
