Hi @ashilkrishnan

Thank you for your help! The automatic rollback to 7.0 works (requires just a reboot). And 7.0 runs without a problem.

For what exact feature in the hardware BIOS should I look for? I must admit I have no idea, about what to check and where I can see if there is an incompatibility.

look forward for your response.

Upgrade ESXI 7.0.1 - Fatal CPU mismatch

I try to ugprade my homelab ESXi 7.0.0 (Build 16324942) to ESXi 7.0.1 (Build 17168206) and receive the attached purple screen after rebooting the host. The CPU used is an INTEL Atom C2750 which should be still supported according the HCL.

Any ideas?

best regards

Martin
