Today updated UEFI from 2.01 to the latest version 2.51 and VMware ESXi 6.0.0 3620759 always crashed during boot at the line
"Relocating modules and starting up the kernel…"
This problem seems undocumented at the moment. You find tons of forum posts about ignoreHeadless but in my case this did not solve anything.
It was difficult to downgrade the firmware as the OS was not booting and you cannot up- or downgrade when the server is not booted into an OS. So I booted a Windows 10 PE Environment from iso and then downgraded to 2.10.
VMware could start again after that downgrade.
Lenovo knows about such problems for their own Server models:
But neither workaround now later UEFI are possible for system-x servers. The mentioned TPM options are not available in system-x BIOS.

Thanks clum2 for reporting the same issue.
Do you know the exact ESXi 6.0 Build number before upgrading to 6.5?
Lenovo Support told me, that the issue may not be present if 6.0 U3 is already installed before updating UEFI.
Also told me, that 6.0 U3 cannot be installed if there are'nt some special settings in UEFI made before installation.
Our system above has only 6.0 U2

I'm sorry, I don't know the exacy build number unfortunately. As I understand it, if I'd upgraded to 6.0 U3 before I ufpdated the UEFI, I'd have been OK. As it is, I had to in-place upgrade to 6.5 just to boot to VMWare.
Having said that, even after doing this, my VMs still report they are vulnerable to both Meltdown and Spectre exploits when I run Get-SpeculationControlSettings.
Everything seems confused, even now, with VMware appearing to still be saying to hold on for now.

What version of UEFI are you running? The information from Lenovo here suggests that the updated UEFI was withdrawn and, despite being due a month ago, is still not avaialble again.

2.52 is now available and plays nicely with ESXi 6.5 - I've now updated all my hosts successfully. It's worth updating ESXi with all the latest patches etc first though.

Can anyone confirm whether or not the latest UEFI for the x3650 M5 (5462), version 2.60, fixes this, or does one still need to install ESXi 6.0 U3 before updating the UEFI?
