You might try with 'earlyprintk' on the command line. That should tell more.
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 : http://ftp.frugalware.org/pub/other/people/crazy/kernel/t/crash.mp4 Also this is after waiting a while : http://ftp.frugalware.org/pub/other/people/crazy/kernel/t/20170211_130319.jpg 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.
