TrustedGRUB2 fails to boot with TPM 1.2 on a HP desktop

Strange. Never seen this before. Probably a bios bug. Are you running the latest version?

I got the source from the git tree.
I was thinking BIOS bug as well i am going to try the same thing on a different vendor server.
The TCG_PC_LOGOVERFLOW made me think if i needed to configure something in my BIOS or TPM chip like carving out a region for logs in NVRAM before i try to boot with this. The BIOS has no further options beyond enabling and disabling the chip. (or making it hidden). All those things are set as HP asks me to

[neusdan]

Do you have the latest BIOS version installed?

[amitlimaye]

havent checked but i got this desktop from HP last week
will reach out to HP to check it

-SIGTERM

I have a similar issue, it does not work with version 1.4 and master. Try version 1.3, should work.

[neusdan]

Could you tell us what error exactly?

@amitlimaye @white00black: Can you try the code from PR #55 and see if that resolves your issue? It looks like there's a widespread bug in newer BIOSes that prevents appending to the TPM event log with certain calls.
