With that I have some more output.. and after lots more boots I found out there are really at least 2 bugs triggered by this in 4.10.
When just boothing with earlyprintk=vga debug ignore_loglevel the kernel hangs right after :
Key type dns_resolver registered ..
The cursor blinks and one have to wait a while this bug to trigger if at all. Sometimes it just hangs there and that is.
Adding ' dis_ucode_ldr ' to commandline makes the kernel hangs right after :
clocksource: tsc: mask: 0xffffffffffffffff max_cycles: 0x20ac7f6ecc6, max_idle_ns: 440795315461 ns ...
and I have the bug triggered really quick..
Also I cannot get netconsole to work , I'm sure is some problem here local and I don't have any serial cable around right now. The only way I saw now to give you at least some ifo is to make an video of that crash. You can find it there :

Also this is after waiting a while :

I know videos and picures are not the best solution but reight now I don't have any other way to capture some logs :|
The kernel is Linus git tree + .d966564fcdc19e13eb6ba1fbe6b8101070339c3d reverted and the config is :
http://ftp.frugalware.org/pub/other/people/crazy/kernel/t/config
I hope the video helps at least somewhat to have a clue what could be wrong.
