Hello Martin

When do you expect the fixed version? 

Best Regards

Ralf

Good Morning

We have the same problem with one of four Dell R730 servers. But we have already installed vSphere 7.0.3.

We tried downgrading to BIOS 2.13.0, but since we enabled TPM, the server won't boot even after entering the recovery key.

Even with a new installation of ESXi, after each reboot appears following Error.

UEFI0046: An issue is observed in the previous invocation of TXT SINIT Authenticated Code Module (ACM) because the TXT information stored in the TPM chip may be corrupted. Do one of the following:
1) Update the BIOS firmware.
2) Go to System Setup >System Security page, click the "Clear" option under TPM command. Restart the system, go to System Setup > System Security page, click the "Activate" option under TPM command, and then enable TXT.

We tried all the options above options, no success. We found following VMware KB Article, but nothing helped. 
ESXi host platform reset behavior with Intel TPM/TXT's reset attack protection feature (78243) (vmware.com)

Does anyone have an idea?

Thanks
Ralf

Hi,

sorry I could not post here such internal Information.

For the other Problem, it doesn't sound easy, but you could try to Update BIOS , remove TPM-related features, and then downgrade it again.

Regards Martin

we downgraded to 2.13 and actually the problem no longer occurs. 
thank you very much as always for your help, we await the release of the fixed bios
