I checked both FreeBSD 11 RC2 and RC3 latest stable releases. Same issue 
exists. When loading the kernel from USB pen drive at boot prompt, system gets 
switched off.

Could you please help?

Hi John,

Thanks for your quick response.

I did the same exercise on a super micro(X59SRL model) server, to segregate the 
issue. The same issue is reproduced again.

So IMHO this may not be the system UEFI firmware issue due to following two 
1.      "load kernel" does not work on 2 different hardware platforms.
2.      On FreeBSD 10.3 and 10.2, both the hardware platforms (HP ProLiant 
ML110 Gen9 and Super micro X59SRL) work without problem.

Could you please advise some work around or any other exercise to narrow down 
the issue.

Ugh.  I don't have a good suggestion on debugging this besides adding printfs 
to the EFI loader code and/or moving an infinite loop around in the code to 
narrow down exactly when it resets.  It is quite possibly specific to the EFI 
firmware on your machine (at least, reproducing the issue might be).
