I saw following error message recurring several times on kernel log. Can anybody make an interpretation of it?

efi: EFI v2.40 by INSYDE Corp.
efi: SMBIOS=0x8c630000 ESRT=0x8c62ef18 ACPI 2.0=0x8cffd014 RNG=0x8c635198 TPMEventLog=0x8331f018 
efi: seeding entropy pool

What version of Ubuntu? – David Apr 14 '21 at 08:17
Ubuntu 20.04.2 LTS but I updated after last restart. I think it was 20.04 before. – Andrew Harlan Apr 14 '21 at 08:30
Did you do as it suggests in the error? *see man kernel_lockdown.7 – David Apr 14 '21 at 08:34
Yes, it returns: No manual entry for kernel_lockdown.7 – Andrew Harlan Apr 14 '21 at 08:36
This link is the man page *https://man7.org/linux/man-pages/man7/kernel_lockdown.7.html – David Apr 14 '21 at 08:40

I have only one harddisk and no windows installed. Secure boot and UEFI enabled. I didn't have this error before so I don't think I should disable any of this. – Andrew Harlan Apr 14 '21 at 09:25
"[Firmware Bug]: TPM Final Events table missing or invalid" is related to a mismatch between your hardware, bios and the microcode driver and it is (probably) intended for the maintainer of the driver. The other lines are notifications. – Rinzwind Jul 26 '21 at 14:11
Just disable Secure Boot, and you are good to go. – Vlastimil Burián Aug 05 '21 at 06:47
